When we watched the Miracle of Life video, I asked you to pay attention to the relationship between the structures of the human reproductive systems (male and female) and their functions.
This week, I want you to describe 5 of those relationships. How is the shape of the structure help with fulfilling its function? How does its location help?
I expect your whole response to be about 1 page. As usual, you will post your response by Friday and then post 3 comments by next Monday.
I look forward to reading your work (as always).

Testes - This is where the sperm grows. The testes hang lower than the rest if the body to keep the tempature down for the sperm. Inside the teste nurse cells nurture and protect the sperm cells untill they are properly grown. The testes are inside a sack called the scrotum.
Overies - These are the gland in the females body that produces the egg. The overies only produce 1 egg per month. the egg will travel down the folopean tube into the uterus.
Uterus - The uterus is the place where the egg goes to wait for the sperm. The uterus is so big in comparison to the other organs because this is where the baby would grow if the sperm got to it. So the egg just waits there untill sperm comes. If it doesnt, the lining (nutreint blood to nurish the baby) is shed. When the lining is shed, blood leaves the body, called the menstraul cycle.
Urethra - The urethra in the male is the tube that conects the testes and the penis. Its there to let the sperm out of the penis during ejaculation.
Sperm - The sperm is an important part of the reproductive system even though it’s not a structure. The sperm grows in the testes, nurtured by nurse cells. When the sperm finish growing they develope tails and a layering over thier heads. The layering is there to break away the covering of the egg. The sperms soul purpose is to find the egg and combine their chromosomes.

For something in the human reproductive system, it’s structure and function are linked. The structure is the way it is to fulfill it’s function is the easiest and best way possible. These are the 5 things in the human reproductive system from ‘The Miracle of Live’ video.
Fallopian Tube
Function: To move the egg towards the uterus.
Structure: Has cilia lining the edges to push the egg. This journey make take days.
Sperm
Function: To fertilize the egg in the women’s body.
Structure: Flagella to allow the sperm to transport themselves, hopefully towards the egg.
Uterus
Function: Where the baby grows.
Structure: Large to hold a baby as it develops and gets larger.
Testes
Function: To produce semen.
Structure: On the outside of a man’s body. They are cooler: the conditions needed to produce semen.
Ovary
Function: In females to produce the eggs that enable them to reproduce.
Structure: Shaped to most efficiently hold the eggs. This is basically in the shape of an oval.

For many parts of the body especially the reproductive system, the structure and the function are linked. The structure is the way it is so that the function can be accomplished as easily as it can be. I learned some examples of this from the “Miracle of Life” video that we watched in class.
Sperm (male)
Function: To get to the egg in the woman’s body and fertilize it.
Structure: It has flagella which hepls the sperm get to the egg efficiently and hopefully end up fertilizing it.
Urethra (male)
Function: Let the sperm out of the penis during ejaculation.
Structure: A tube that connects the testes to the penis.
Fallopian Tube (female)
Function: To help move the egg towards the uterus.
Structure: A tube that has cilia lining to help push the egg closer to the uterus.
Ovary (female)
Function: It produces the eggs that the sperm can fertilize.
Structure: In the shape of an oval to keep the eggs in a secure place.
Uterus (female)
Function: Place where the fetus develops and grows.
Structure: Stretches and gets large enough so it can hold the fetus as it gets bigger.

There are many relationships in the structures of the human reproductive system. The shape and structure are very important and well designed for their purpose.
The Fallopian Tube- The Fallopian Tube moves the egg to the ovary and is about five inches long. It is lined with cilia on the edges of the tube which push the egg. It takes a few days for the egg to move through the Fallopian Tube.
Sperm- The sperm is what fertilizes the egg. They are grown in the testes. When they are finally grown they have a protective layer on their heads which helps them break the layer of the egg and a tail to hopefully propel them to the egg to fertilize it. The male reproductive system produces many sperm because many of them either die or are mutated. Only one sperm gets to fertilize the egg.
Ovary- The Ovary is were the eggs are produced very slowly. It is a safe environment for the eggs to be held and then the egg is transported though the Fallopian tube.
Uterus- The Uterus is were the egg waits to be fertilized by the sperm. When it is fertilized, it will develop into a baby here. The Uterus enlarges while the baby grows.
Testes- The Testes are were the sperm are made. They keep a special temperature which is cooler than the rest of the body so that the sperm can produce correctly.

The parts of the male/female reproductive systems’ functions are linked to their shapes and parts. When watching the video, I learned a lot of these connections.
Uterus-The uterus is where the baby grows in the woman. The Uterus is shaped to fit it’s function. It is large, which is needed so that the baby can grow.
Sperm-The sperm is what fertilizes the egg. The sperm are stored in the male’s testes. When they are released into the female’s body, their goal is to reach the egg. In order to do this, the sperm has to over come many obstacles. In order to propel itself, the sperm has a tail.
Testes-The testes produce and store the sperm. They hang low to keep the temperature cold for the sperm.
Ovary-The ovaries produce the eggs. They are shaped like circles, which is probably the best shape for storing the eggs.
Over all, I learned a lot from the video. Although I did not mention all of the parts of the reproductive systems (like the urethra, or the penis, or vagina, etc.), I still feel that I understand most of the reproductive organs. I am a little confused about some though.

Testes- The testes or testicles are mainly the production of sperm. Another main function is producing male sex hormnes, of which testosterone is the best-known. The testes are very important because if you didn’t have them then their would be no offspring.
Ovary- Ovaries are egg-producing reproductive organs found in female organisms. They are part of thevertebrate female reproductive system. Ovaries in females are homologous to testes in males. If women did not have the ovary their would be no offspring.
Scrotum- The scrotum is a bag of skin and muscle containing the testicles. It is an extension of the abdomen, and is located between the penis and anus. In humans, and some other mammals, the base of the scrotum becomes covered with pubic hair at puberty.
Urethra- In anatomy, the urethra is a tube which connects the urinary bladder to the outside of the body. The urethra has an excretory function in both genders to pass urine to the outside, and also a reproductive function in the male, as a passage for sperm. The urethra is a big part of releasing wastes.
Sperm- The sperm is not a body part but is created by a body part called the testes. When the time comes the sperm comes out of the penis inside the vagina and looks for and egg to attach to. I think the sperm is one of the most important parts of reproduction because, they are like the recipe for reproduction because, you need the recipe to make food well same with a baby you need genetcs to make a baby. So with no sperm no baby.

In the human body there are a lot of structures and with each structure are functions. Here are five examples that state their structure, their function and how they relate to each other:
Testes-This is where sperm is made, and has to be below regular body temperature in order for the sperm to be made correctly. If guys wear tight jeans or something like that, the testes are closer to the body, and are warmer, and they can’t produce sperm correctly anymore.
Sperm- Sperm is a structure that has a head and a tail and contains the males genetic information. The tail helps it move so that it can get to the egg. The sperms function is to get to the egg and fertilize it.
Ovary- The ovary is a structure that is round. Its function is to make thee eggs. It is much easier for the ovaries structure to be round because that mean that the eggs are easier to move around.
The Fallopian Tube- the Fallopian tube is a tube that goes directly to the ovary. It helps the egg to straight to the uterus and has cilia that help the egg move along.
The Uterus- the Uterus is where the egg waits to be fertilized and is round, and large. It is shaped that way so the baby will have space and will be able to move easily. It has a lining on the inside so it can catch the egg and have it ready for the sperm.
I learned a lot from this movie that I had no idea about before. I didn’t know how everything connected to each other plus other things.

Their are many male and female reproductive parts that are just as usfull as the five i chose. The five I chose were;
The Egg, Penis, Testies, Ovary and Sperm.
1)The Testies are located under the penis and holds the sperm. A main function is producing male sex hormnes, which testosterone are the best-known. It is kept 2 degrees lower then the regular body so the sperm dosn’t become defected.
2) If it wasn’t for the penise, most reproduction wouldn’t be able to take place. It is a male reproductive system. The penis is a tube like shape witch makes it easy for the penis to be inserted into the vagina. The penis is placed inbetween you legs and right underneath your wast line. in most sexual activity, the penis will erect so it is easyer for it to be inserted in the vagina. the substance that is releast from the penis is is semen and in the semen is the sperm.
3) The sperm is Kept arownd the testieswitch is kept 2 degrees lower then the regular body so the sperm dosn’t become defected. It is a par of the male. Milions of sperm is made every day and when the sperm is ejected into the vagina, the thousands of them make there way through the fallopian tube and into the ovary.
4) The ovary is where the the egg is stored. There is a right and a left overy, so only half os the sperm will make it to the egg. the others will die.
5) Once the sperm is in the overy, it finds the egg with a layer of tissue arownd it. The sperm will eat a path through the tissue and wich ever sperm gets in first, wont let any other in at all.

1. The Fallopian Tubes
Structure:
Long and narrow with contracting walls that push the egg towards the uterus. Sperm have to fight the current to meet the egg for fertilization. The sperm fights its way up the current of the fallopian tube to successfully make it to the egg before the sperms time is up (1-2 days) to make contact with the egg.
Function:
Place of egg fertilization, transportation to the to the uterus from its ovary.
Location/shape:
Attached to either side of the uterus that extends towards the ovary.
Its has a tube-like structure to PERFECT THE TIME
2. Uterus/womb
Structure:
Pear-shaped muscular sack, strongest muscles of the body, walls are called uteritine lining (endometrium) sheds each month during menstrualation (if not pregnant). The cervix is the entrance to the uterus connecting the uterus to the vagina. The cervix must efface and dilate for the baby to pass through the birth canal.
Function:
Forcefully draw the sperm upward, allow menstrual blood to flow downward, and to push the baby through the birth cannel. Its walls (the endometrium) feed the developing zygote nutrients.
Location/Shape:
Attaches to the fallopian tubes, above the vagina, in the lower half of your body
In the uterus there is tissue padding the walls to give nutrience and protection to the embryo. The walls can expand to serve the size of the devolping embryo inside. The clevix acts as a plug to make sure the baby stays inside the womb. When its time to give brith, the clevix opens up to let the offspring through.
3. Penis
Structure:
During sexual intercourse/attraction the arteries supplying blood to the penis dilalate, filling the columns of erectile tissue in the penis with nutritional blood for the collection of semen making it become stiff and forcing the penis to erect. The penis consists of three columns of erectile tissue (two corpora cavernosa tissues and one corpus spongiosum tissue). The corpus spongiosum lies on the underside (vertical side) of the penis and corpora cavernosa lie next to each other on the upper side (dorsal side). The corpus spongiosum has an opening at the end called the meatus, this serves as a passage for urination and the ejaculation of semen. The fluid called semen is produced inside the penis by the secretion of chemicals from the ejaculatory ducts, prostate glands, and the seminal vesicles (vas defrens).
Function:
The penis is the end of the urinary tract as well as the portal of which to transport the male sex cells to the female during sexual intercourse. The penis creates semen (a mix of sperm and nutritional liquids) that would be sent to the female during interaction.
Location/shape:
Lower half of the body above the testes. The penis ejects upwards during ejaculation.
The penis is long so to be able to reach into the vagina and release its semen and have the female be able to retain the males sex cells.
Testicles
Location/Shape:
Inside of the scrotum. The scrotum is located outside the body, and hangs down below the penis. It looks like a sac made out of skin.
Function:
It produces sperm and keeps them alive until theyre ready to leave the testicles in the liquid, semen.
How its location/structure helps it function:
The testicles hang under the penis, outside of the body, because the testicles must be a few degrees less than the rest of the human body temperature to create sperm. If it is to hot it will not function correctly or as well as in preferable environment.
Ovaries
Structure:
The ovaries go through a cycle to produce the egg. The ovaries are like the testis in that they are gonads and produce the sex cell for the organism.
Function:
The ovaries develop the eggs and release them to be picked up by the fallopian tubes.
Location/Shape:
The ovary (for a given side) is located in the lateral wall of the pelvis in a region called the ovarian fossa. The fossa usually lies beneath the external iliac artery and behind the uterus. There are two ovaries on either side of the uterus that alternate in producing eggs. They are located in the lower back of the female. The ovary is attached to the uterus, but not the fallopian tubes.

1. Penis (Male)
The penis is the end of the urinary tract as well as the portal of which to transport the male sex cells to the female through the vagina during sexual intercourse. The penis creates semen (a mix of sperm and nutritional liquids) that would be sent to the female during interaction. During sexual intercourse/attraction the arteries supplying blood to the penis dilate, filling the columns of erectile tissue in the penis with nutritional blood for the collection of semen making it become stiff and forcing the penis to erect.

The corpus spongiosum has an opening at the end called the meatus, this serves as a passage for urination and the ejaculation of semen. The fluid called semen is produced inside the penis by the secretion of chemicals from the ejaculatory ducts, prostate glands, and the seminal vesicles (vas defrens). Lower half of the body above the testes. The penis ejects upwards during ejaculation and is long so to be able to reach into the vagina and release its semen more accessibly into the female.
2. Testicles (Male)
The testicles produce sperm and keep them alive until they’re ready to leave the testicles in semen through the penis. The scrotum is located outside the body, and hangs down below the penis. It looks like a sac made out of skin. The testicles hang under the penis, outside of the body, because the testicles must be a few degrees less than the rest of the human body temperature to create sperm. If it is to hot it will not function correctly or as well as in preferable environment.
3. The Fallopian Tubes (Female)
The main functions of the Fallopian tubes are place of fertilization and to transport the zygote or egg to the uterus from the ovary. The fallopian tubes’ structure is long, thin and tube-like. The inner walls of the fallopian tubes have contracting walls that push the egg towards the uterus forcing sperm traveling to the egg’s location to fight the dangerous current. There are two separate tubes that are connected from the uterus, and out above the ovary to capture the egg. Its tube-like shape provides an easier way to transport to the uterus than if it was round and fat.
4. Uterus/womb (Female)
The main functions of the uterus are to forcefully draw the sperm upward as well as allow menstrual blood to flow downward, and to push the baby through the birth cannel. Its walls (the endometrium or uteritine lining) are important to feed the developing zygote nutrients. The uterus is a pear-shaped muscular sack, and is one of the strongest muscles of the body. The cervix is the entrance to the uterus connecting the uterus to the vagina. The cervix must efface and dilate for the baby to pass through the birth canal. The uterus is connected to the fallopian tubes and holds onto the ovaries. The uterus is located above the vagina, in the lower half of the body. In the uterus there is tissue padding the walls to give notorious and protection to the developing embryo. The walls can expand to serve the size of the developing embryo inside. The cervix acts as a plug to make sure the baby stays inside the womb. When it’s time to give birth, the cervix opens up to let the offspring through.
5. Ovaries (Female)
The ovaries develop the eggs and release them to be picked up by the fallopian tubes. The ovaries go through a cycle to produce the egg based on hormones levels. The ovaries are like the testicles in that they are gonads and produce the sex cell for the organism. They are located in the lower back of the female. The ovary is attached to the uterus, but not the fallopian tubes. The ovary (for a given side) is located in the lateral wall of the pelvis in a region called the ovarian fossa. The fossa usually lies beneath the external iliac artery and behind the uterus. There are two ovaries on either side of the uterus that alternate in producing eggs. Alike to the testicles, the ovaries are held on the reproductive track by mainly nonreproductive material. The ovaries’ shape and location provides a safe, to the side place where the female sex cells can be produced and released than somewhere closer to the uterus.

Testes are structured the way they are so that they can be a few degrees cooler than the body, as this is the optimal temperature to produce sperm in. The Scrotum is also designed so if it is too cold, it tightens closer to the warmth of the body.
The Uterus is structured so that it wont take up to much space in the body, but when an egg gets fertilized the uterus expands to allow for the embryo to grow.
The Fallopian Tube is structured so that it can move the egg along by cilia. It takes a couple of days for the egg to move along the total length (5 inches).
The Ovary is designed to hold the eggs, and so that the egg can mature in it. Then during ovulation the egg is released into the Fallopian Tube.
The Sperm are structured so that they can push themselves along using their tails. Also they are base so they can survive in the acidity of the uterus. The head has enzymes to help it get into the membrane of the egg. The head also explodes when it reaches the egg to spread around its genetic material.

There are many relationships that go along with the process if reproduction.
The sperm cell’s funtion is to fertilize the eggs. The body of a sperm cell is made and it has a function for every part. The body head of the sperm cell is so that they could survive in the uterus where as the tail is their way of “transportation”. Their tails are used to push them into and through out the fallopian tube.
The ovaries is made so that they could hold the eggs. I think that the ovary is designed exactly for its use. The point of the ovary is to hold the eggs, and the pouch like figure that the eggs get stored in helps that reason of the ovary being there.
The scrotum is also another pouch that help hold the testes. The scrotum is included in the male reproduction system. The scrotum is kept at max. 3 degrees lower in temperature, so that the testes can produce sperm that is not defected.
Another structure is the fallopian tube. The fallopian tube is found in the female reproduction system. The fallopian tube is there so that eggs can move to the uterus. The eggs move to the uterus with cilia. THe fallopian tube is also where the egg gets fertilized.
The last structure that I’m going to talk about is the uterus. The uterus is the last stop that the fertilized egg goes. It is the last stop because the fertilized egg then attaches itself to the uterus. The uterus is where the actually growing of the egg begins.

Uterus-The uterus is where the baby grows in the woman. The Uterus is shaped to fit it’s function. It is large, which is needed so that the baby can grow.
Sperm-The sperm is what fertilizes the egg. The sperm are stored in the male’s testes. When they are released into the female’s body, their goal is to reach the egg. In order to do this, the sperm has to over come many obstacles. In order to propel itself, the sperm has a tail.

I've been caught LEFT handed!
// Mar 26, 2007 at 5:44 am
In the movie I understood all of it but the five parts I chose for my essay were the parts I mostly understood in the movie. All parts have a reason to be whatever shape they are:
Ovaries-The ovaries are where the eggs are, when produced. The ovaries keep the egg(s) safe only in a females’ body.
Testes-The testes keep a special temperature a little bit cooler than normal body temperature for the sperms to fertilize in. This precise temperature helps all the sperms to try to produce correctly. The testes are in a males’ body.
Fallopian Tube-The Fallopian tube is located in a females’ body. The egg slowly moves through the fallopian tube trying to get to the uterus. What makes the egg go a little faster there is cilia on the lining of the tube?
Sperm-The sperms are grown in a male (the testes). The male produces a lot of sperms because some might not make. Sperms have a tail like structure called flagella to help it swim through the body. The sperm is what also fertilizes the egg.
Uterus-The egg waits in the uterus for the sperm. If the sperm does fertilize the egg, it will then develop into a baby, in the uterus. If the egg develops into a baby the uterus will grow with the baby, to make room for it. The uterus is in a females’ body.

During the movie “The Miricle of Life” I learned a lot about the five parts that I chose for this weeks weekly science article. The five parts I chose are the penis, vagina, testes,sperm, and the scrotum.
scrotum- The scrotum is the sac of skin containing the testes. Its function is to make sure that the testes are at a litlle lower tmpature than the body, so that it can create sperm. It does a good job because it is away from the body.
testes- The testes are placed inside the scrotum so that they can be a few degrees blow the normal body temperature. They testes also create sperm for the body.
penis- The penis is the path for the sperm to enter the vagina so that it can fertilize the egg. It has many nerves so that it knows when to ejaculate.
sperm- has a small tail so that it can swim through the bodily fluid to the egg inside the woman. it also carries the mans genetic information to the egg. The sperm is one of the most important parts of the reproductive cycle
vagina- The vagina allows the penis to enter the females body so that ejaculation can occur. The vagina is where the sperm enters the woman and heads to the egg. The woman also gives birth through the vagina.

Testes-
The testes are located in the scrotum which is a sac that hangs outside of the body and under the penis. The function of the testes is to produce sperm (the male sex-cells) and then protect them. In order to produce sperm well, the testes must be a few degrees cooler than the rest of the body. Hanging outside of the body, the testes have a perfect enviornment because of the cooler temperature.
Fallopian Tubes-
The fallopian tubes are long, narrow tubes that transport the egg (which then becomes a zygote after fertilization) from the ovary to the uterus. The fallopian tubes are also the location in which the egg is fertilized by the sperm. The fallopian tubes have walls that contract to push the egg through, and are shaped perfectly to do this. Each female has two fallopian tubes which are connected to the uterus on either side of it.
Ovaries-
The ovaries are the female gonads which produce eggs (the female sex-cell) and then release them to be transported by the fallopian tubes. Each female has two ovaries which take turns in producing eggs. The ovaries are located and shaped in a way to effectively produce eggs and release them.
Uterus-
The uterus has many important functions. It allows menstrual blood to flow through it downward, pushes the sperm upward, and is also the place where the embryo and then fetus develops. It is located above the vagina and has walls that are specialized to feed the zygote important nutrients so that it can develop. Its walls are also padded with protective tissue to make the embryo and then fetus safe. These same walls can also expand so that there is room for the child growing inside.
Penis-
During sexual intercourse, the penis transports semen (contaning sperm) into the vagina. When the man in aroused, tissue in the penis becomes filled with blood so that it becomes erect and prepared for intercourse. When it is stiff, it is perfect for ejaculating semen into the woman’s vagina.

Fallopian Tubes~
The Fallopian tubes are located in the females body. They are narrow tubes that move the egg along very slowly making its way to the uterus. If the egg is not fertilized in time, the woman excretes it through the vagina: period.
Ovaries~
The Ovaries are located in the females body. There are two ovary pouches that hold the eggs. The ovaries keep the eggs safe until its time for them to be realeased.
Scrotum~
The Scrotum is located in the males body. It is a sac that holds the testes. The scrotum must keep the testes at least three degrees lower than normal body tempature. If not the male may produce defected sperm.
Uterus~
This is where the egg embeds itself in the lining of the uterus waiting for the sperm to come fertilize the egg. If the sperm comes in time and fertilizes the egg a baby starts to grow. If not then the unfertilized egg is excreted out of the womans body.
Sperm~
The Sperm is located in the males body, inside the testes. This is what fertilizes the womans egg. The sperm is able to move because of it long tail. If the sperm is not kept at the right degree it will get defected and some sperm may have two heads or two tails.
