The Reproductive System

This Presentation will explain the importance and significance of the reproductive system. For further explanation watch the video and click the button below.
The female reproductive system is made of many different elements, the most known are the vagina, uterus (womb), ovaries, and fallopian tubes. You are probably wondering what these parts do or maybe even their purpose, well I'll tell you. To start off the vagina, also known as the birth canal, is attached to the uterus through the cervix. The cervix is a narrow entry way in between the vagina and uterus.
FACT: The vagina can grow wider to deliver a baby.
Next is the uterus (womb). The uterus is a pear shaped organ, where the development of a fetus takes place. The uterus is divided into two parts: the cervix and the corpus. The cervix, as mentioned earlier, is the lower part of the uterus that opens up to the vagina. The corpus is the main body of the uterus that can expand easily to hold a baby. Now on to the ovaries. These are small almond shaped glands that are placed on either side of the uterus. These glands produce female sex hormones called estrogen and progesterone and also produce eggs. Last, we have the fallopian tubes, that connects the uterus to the ovaries.
FACT: The fallopian tubes also act as the location for fertilization of the egg cell if sperm are present following sexual intercourse.
There are two fallopian tubes, each with a narrow passage way no wider than a sewing needle. Observe the pictures below and click the link titled " Female Reproductive System Primary Parts."
Now that you know the parts of the Female Reproductive System, we should go over the importance of the system. The female reproductive system of the lower abdomen and pelvis contains all of the organs necessary for fertilizing egg cells, development of a fetus (baby) during pregnancy, and delivery of a newborn baby. Both the female and male reproductive systems are essential for reproduction. The female needs a male to fertilize her egg cells (ova), although she is the one who carries offspring through pregnancy and childbirth. All living things reproduce. Reproduction, the process where organisms make more organisms like themselves, is one of the things that sets living things apart from nonliving matter.
Male Reproductive System
The male reproductive system is very simple compared to the female reproductive system. The system's primary parts are the urethra, penis, testicles, and scrotum. Unlike the female reproductive system, most of the male reproductive system is located outside of the body. These external structures include the penis, scrotum, and testicles. Now it's definition time!
- Penis:This is the male organ used in sexual intercourse. It has three parts: the root, the body/shaft, and the glans.The root is the structure that attaches to the wall of the abdomen. The body/shaft is the cylindrical part of penis between the scrotum and glans.The glans is the cone-shaped part at the end of the penis. The glans, also called the head of the penis, is covered with a loose layer of skin called foreskin.
- Scrotum:This is the loose pouch-like sac of skin that hangs behind and below the penis. It contains the testicles, also called testes, as well as many nerves and blood vessels.
- Testicles: These two oval shaped organs produce sperm cells and testosterone, the primary male sex hormone.
- Urethra: The urethra is the tube that carries urine from the bladder to outside of the body. In males, it has the additional function of ejaculating semen when the man reaches orgasm. When the penis is erect during sex, the flow of urine is blocked from the urethra, allowing only semen (Semen is a natural fluid produced by the male reproductive system) to be ejaculated at orgasm. Now that we are finally done with definitions check out the rockin' Brain Pop below, then look at the video that focuses on the male reproductive system!! Username-ltms//Password-ltms
Now that you have watched the video lets review! The male gamete that is produced is called sperm. Sperm is combined with the female gamete to form offspring that has half the DNA of the male and half female. The testes (testis singular) produce sperm, that once ready move to the epididymis. The epididymis are located on top of each testicle and its purpose is to store and produce sperm. Afters it is uncoiled, the epidiymis can measure about 23 feet! The coiled tube is divided into three parts; the head, body,and tail.
