System
DEFINITIONS: (EXTERNAL)
Penis: The male organ for sexual intercourse, reproduction, and
urination. The reproductive purpose of the penis is to deposit
semen in the vagina during sexual intercourse.
Scrotum: A sac-like pouch located behind the penis that holds
each testical and helps regulate temperature for sperm
production.
DEFINITIONS: (INTERNAL)
Testicles/Testes: The two testes are small organs about the size
of a peach pit that lie in the scrotum and produce sperm and the
hormone testosterone. The testicles are the male sex gland.
Epididymis: Tightly coiled tube where sperm are stored. From
here sperm are transported to the Vas Deferens.
DEFINITIONS: (INTERNAL)
Vas Deferens: Two long, thin tubes that serve as a passageway.
Transports sperm from the Epididymis to the urethra.
Urethra: A dual purpose tube that both semen and urine pass
through to leave the body. Semen and urine never mix.
DEFINITIONS: (INTERNAL)
Seminal Vesicles: Two small glands that secrete a mucous fluid
that nourishes and enables the sperm to move.
Prostate Gland: Walnut-sized gland beneath the bladder. The
gland secretes an alkaline fluid that neutralizes the acid found in
the male urethra and the female reproductive tract.
DEFINITIONS: (INTERNAL)
Cowper’s Gland: Two small pea-sized glands located beneath
the prostate gland on both sides of the base of the penis. They
secrete a clear, sticky fluid that is alkaline to help neutralize the
acidity of the urethra.
Ejaculatory Ducts: These are formed by the fusion of the vas
deferens and the seminal vesicles. The ejaculatory ducts empty
into the urethra.
SPERM PRODUCTION AND EJACULATION
1. Sperm made in testicles
2. Sperm matures in
epididymis
3. Sperm travel up vas
deferens
4.
Sperm mix with seminal
fluid to make semen
5.
Sperm leave the penis
(ejaculation)

DEFINITIONS: (EXTERNAL)
Vulva: The general term to describe all the external
female sex organs.
Urethra: Below the clitoris, the opening to the bladder.
Clitoris: The center of sexual sensation. It is composed
of many sensitive nerve endings.
DEFINITIONS: (EXTERNAL)
Labia Majora: Two folds of skin running that form
around the vaginal opening. The labia majora meet and
fold together forming protection for the genitals.
Covered with pubic hair.
Labia Minora: Two smaller folds of tissue which lie
just within the labia majora. Join at the top, forming a
hood over the clitoris.
DEFINITIONS: (INTERNAL)
Hymen: A thin ring of tissue covering the opening to
the vagina. It is the dividing line between external and
internal sex organs.
Vagina: Female organ of intercourse, it is actually an
empty passageway leading from the vaginal opening to
the uterus. It is usually 3-4 inches. The vaginal walls
can stretch greatly.
DEFINITIONS: (INTERNAL)
Cervix: The neck or opening of the uterus. A normal
healthy cervix is the strongest muscle in the body.
Uterus: The uterus is a hollow, muscular organ shaped
somewhat like an upside-down pear. The uterus has one
main function – to protect and nourish a fetus. The
walls of the uterus stretch much like a balloon that is
blown up.
DEFINITIONS: (INTERNAL)
Fallopian Tubes: Two tubes shaped like arched
bridges, on either side of the uterus. They are about the
size of cooked spaghetti. The fallopian tubes carry egg
cells toward the uterus and sperm cells toward the egg
cell. They are the location for fertilization.
DEFINITIONS: (INTERNAL)
Ovaries: Two solid egg-shaped structures about the
size of peach pits. They are the counterpart of the male
testicles. They have two main functions: 1-produce
female estrogen and progesterone. 2- to store and
release the ova or female egg cell.
MENSTRUATION
1.
Lining of uterus us shed (day 1 of menstrual flow)
• Usually lasts 5-7 days
• Made up of blood and tissues
• About 4-12 teaspoons
2. Lining of uterus thickens with blood and other tissues
3. Ovulation occurs (egg released from ovary)
4. Egg travels through fallopian tube
5. Egg enters the uterus
6. Egg dissolves if unfertilized
7. Lining of uterus is shed (day 1 of menstrual flow)
