The importance of protecting our sensitive parts
It is important to protect our sensitive parts for us to be free from disease like AIDS and HIV. Taking a bath daily and eating nutritious foods will keep your reproductive organs free from any
harmful diseases.

The vas deferens is a part of our male body where in it
carries semen during our ejaculation period
![Page 8: Exploring the human reproductive sytem](https://reader035.fdocuments.net/reader035/viewer/2022062708/558bea45d8b42ac9158b4569/html5/thumbnails/8.jpg)
The urethra is a tube that carries our urine
and semen for us boys or female ejaculate in girls from inside our
body to the outside
![Page 9: Exploring the human reproductive sytem](https://reader035.fdocuments.net/reader035/viewer/2022062708/558bea45d8b42ac9158b4569/html5/thumbnails/9.jpg)
Penis is our external organs as males, in
addition it serves as the external organ of
urination.
The penis is the male organ for sexual intercourse. It has three
parts: The root, which attaches to the wall of the abdomen; the body, or shaft, and the glans penis which
is the cone shaped end of the penis. The penis also contains a
number of sensitive nerve endings. The penis is considered an external reproductive organ.
![Page 10: Exploring the human reproductive sytem](https://reader035.fdocuments.net/reader035/viewer/2022062708/558bea45d8b42ac9158b4569/html5/thumbnails/10.jpg)
Epididymis is a part of our male reproductive organ . It
is a narrow tightly-coiled tube connecting the
efferent ducts from the rear of each testicle to its vas
deferens.
![Page 11: Exploring the human reproductive sytem](https://reader035.fdocuments.net/reader035/viewer/2022062708/558bea45d8b42ac9158b4569/html5/thumbnails/11.jpg)
Testis is a pair of organs and it’s plural is testes. It is a part
of our male reproductive organ. They are the site of
sperm production and are also the major producer of the
male hormone Testosterone. Some people call these
organs Testicles – which may have something to do with the
fact that they hang down outside the body in a sack
(scrotum) just as an icicle in a freezer does. Commonly they
are just known as "balls" which is a fair description of their shape, although they tend to be more oval than
round.
![Page 12: Exploring the human reproductive sytem](https://reader035.fdocuments.net/reader035/viewer/2022062708/558bea45d8b42ac9158b4569/html5/thumbnails/12.jpg)
Scrotum- The scrotum is the loose pouch like sac of skin that hangs behind the penis. It
contains the testes as well as many nerves & blood vessels. The scrotum has a protective function and acts as a climate control for the
testes.Special muscles in the wall of the scrotum allow it to contract and relax, moving the testes closer to the body for warmth and farther away
to cool the temperature. The scrotum is considered an external reproductive organ.
![Page 13: Exploring the human reproductive sytem](https://reader035.fdocuments.net/reader035/viewer/2022062708/558bea45d8b42ac9158b4569/html5/thumbnails/13.jpg)
Prostate gland- The prostate gland is a walnut sized structure that is located below the urinary bladder in front of the rectum. The prostate gland contributes additional fluid to the ejaculate. Prostate fluids also help to nourish the sperm. The urethra,
which carries the ejaculate to be expelled during orgasm, runs through the center of
the prostate gland.
![Page 14: Exploring the human reproductive sytem](https://reader035.fdocuments.net/reader035/viewer/2022062708/558bea45d8b42ac9158b4569/html5/thumbnails/14.jpg)
Fallopian tubes: These are narrow tubes that are attached to the upper part of the uterus and serve as tunnels for the ova (egg cells) to travel from the ovaries to the uterus. Conception, the fertilization of an egg by a sperm, normally occurs in the fallopian tubes. The fertilized egg then moves to the uterus, where it implants into the lining of the uterine wall.
![Page 15: Exploring the human reproductive sytem](https://reader035.fdocuments.net/reader035/viewer/2022062708/558bea45d8b42ac9158b4569/html5/thumbnails/15.jpg)
ovaries: are oval-shaped. These are located beside the uterus.
The ovaries produces egg cells to form human beings
![Page 16: Exploring the human reproductive sytem](https://reader035.fdocuments.net/reader035/viewer/2022062708/558bea45d8b42ac9158b4569/html5/thumbnails/16.jpg)
Uterus (womb) The uterus is a hollow, pear-shaped
organ that is the home to a developing fetus. The uterus is divided into two parts: the
cervix, which is the lower part that opens into the
vagina, and the main body of the uterus, called the corpus.
The corpus can easily expand to hold a developing baby. A channel through the cervix allows sperm to enter and menstrual blood to exit.
![Page 17: Exploring the human reproductive sytem](https://reader035.fdocuments.net/reader035/viewer/2022062708/558bea45d8b42ac9158b4569/html5/thumbnails/17.jpg)
The urethra is a tube that carries the urine and semen of the
boys and female ejaculate for us girls from
inside our body to the outside
![Page 18: Exploring the human reproductive sytem](https://reader035.fdocuments.net/reader035/viewer/2022062708/558bea45d8b42ac9158b4569/html5/thumbnails/18.jpg)
Cervix is the lower, narrow portion of the uterus where it joins with the top end of
the vagina. It is cylindrical or conical in shape and
protrudes through the upper anterior vaginal wall.
![Page 19: Exploring the human reproductive sytem](https://reader035.fdocuments.net/reader035/viewer/2022062708/558bea45d8b42ac9158b4569/html5/thumbnails/19.jpg)
Vagina: The vagina is a canal that joins the cervix (the lower part of uterus) to the outside of the body. It also is known as the birth canal. It is the outer portion
of our organ.

Genitalia and pubic hair
In the early stages of puberty, the scrotum grows
larger and you might experience some reddening of the skin and notice texture change in the scrotal skin. Pubic
hair might start appearing at the base of your penis. While the scrotum grows, the penis increases in length and has a smaller increase in width. About a year after
your penis starts growing, most boys have their first ejaculation. This is at times scary or worrisome to boys,
but it is perfectly natural and a part of the pubertal process.
![Page 23: Exploring the human reproductive sytem](https://reader035.fdocuments.net/reader035/viewer/2022062708/558bea45d8b42ac9158b4569/html5/thumbnails/23.jpg)
Growing
Puberty can also cause you to go through a growth spurt, which results in an average
growth of about 4.1 inches a year. Your head, hands, and feet are the first things to grow. Then you grow in your arms and legs, and
finally your torso and shoulders catch up with the rest of your body.
![Page 24: Exploring the human reproductive sytem](https://reader035.fdocuments.net/reader035/viewer/2022062708/558bea45d8b42ac9158b4569/html5/thumbnails/24.jpg)
Possible Breast Development
During puberty, some boys do experience slight breast growth, but this is usually temporary and disappears after a while.
![Page 25: Exploring the human reproductive sytem](https://reader035.fdocuments.net/reader035/viewer/2022062708/558bea45d8b42ac9158b4569/html5/thumbnails/25.jpg)
Voice Change
Your voice deepens, and while the process is gradual, you might experience your voice breaking at times. This is normal and natural, so don't worry about it.
![Page 26: Exploring the human reproductive sytem](https://reader035.fdocuments.net/reader035/viewer/2022062708/558bea45d8b42ac9158b4569/html5/thumbnails/26.jpg)
Body Hair
Facial hair first appears at the corners of your upper lip and then spreads across the upper lip, to the upper parts of the cheek, below the bottom lip, and finally to the sides of your face and your chin. Underarm hair is also growing at this time as well.
![Page 27: Exploring the human reproductive sytem](https://reader035.fdocuments.net/reader035/viewer/2022062708/558bea45d8b42ac9158b4569/html5/thumbnails/27.jpg)
Acne
Accompanying underarm hair growth, your sweat and oil producing glands also start developing, which eventually results in acne when these glands are clogged. In order to avoid breakouts, you should wash your face twice daily.

Breasts
Breast development begins between 7 years of age and 13 years of age and continues through puberty. Breast development starts with the flat area around the nipple (areola) becoming enlarged and some breast tissue forming under the nipple. When breast development is complete, each breast is distinct and the areola no longer appears swollen.
![Page 31: Exploring the human reproductive sytem](https://reader035.fdocuments.net/reader035/viewer/2022062708/558bea45d8b42ac9158b4569/html5/thumbnails/31.jpg)
Pubic Hair
Pubic hair starts along the vaginal lips, the outer opening of your private parts. The hair becomes darker and coarser and grows like an inverted triangle. Sometimes, the hair spreads to the insides of thighs, as well.
![Page 32: Exploring the human reproductive sytem](https://reader035.fdocuments.net/reader035/viewer/2022062708/558bea45d8b42ac9158b4569/html5/thumbnails/32.jpg)

Finally underarm hair begins to grow, and your sweat and oil producing glands also start developing, which eventually results in acne when these glands are clogged. In order to avoid breakouts, you should
wash your face twice daily.
