The Reproductive System
A. Functions of the Reproductive System
1. The
is a group of tissues and organs that enables the
male and female reproductive cells to join and form new offspring.
2. Human males make reproductive cells called

females make reproductive cells called

B. The Male Reproductive System
1. The main function of the male reproductive system is to produce and transport
to the female reproductive system.
2. The
are the male reproductive organs that produce
sperm.
3. The two testes are inside an external saclike structure called

5. The

is a tubelike structure that delivers sperm to the
female reproductive system.
6. A mature sperm cell has three main parts—a head, a(n)
,
and a tail.
7. A sperm’s head contains
and substances that help the
sperm join with an egg.
C. The Female Reproductive System
1. The female reproductive system produces immature egg cells
called

is the organ where oocytes are stored and mature.

5. The
connects the uterus to the outside of the body.
6. The vagina is called the
canal because babies leave their
mother’s body through this structure.
7. The
provides a nourishing environment for the
offspring’s development.
8. Eggs contain
and nourishment.
a. A female usually releases
egg at a time.
b. An egg is produced only when the
is prepared to
nourish an offspring.
9. To prepare for new offspring, the ovaries and uterus go through changes called

a. During phase 1, or
, tissue, fluid, and blood cells pass
from the uterus through the vagina and leave the body.
b. Near the end of phase 2, hormones cause the egg to leave the ovary

c. During phase 3, if the egg encounters a sperm, it will join with the sperm

10. During
, the reproductive system stops releasing eggs,
and the menstrual cycle stops.
D. The Reproductive System and Homeostasis
1. The
does not play a part in homeostasis.
2. The reproductive system and the
system work together
and control when the sperm and eggs mature.
