Understanding your body and the process of human
reproduction
Small, oval-shaped glands located on
either side of the uterus. The ovaries
produce eggs and hormones.
Narrow tubes extending from the
ovaries that serve as tunnels for the
ova (egg cells) to travel to the uterus
Fertilization usually occurs here
Hollow, pear-shaped organ that’s
home to the developing fetus.
2 parts: the cervix and the main body
of the uterus, called the corpus-body
develops here.
The lining of the uterus that thickens
as the egg matures. This brings food
and oxygen to the growing baby.
Periodic shedding of the uterine
lining because fertilization did not
occur.
Opening to the uterus
It dilates to 10 cm to allow a baby to
pass through
Canal that joins the cervix (lower part
of the uterus) to the outside of the
body
Birth canal
8. 3 PHASES OF THE
MENSTRUAL CYCLE:
 Phase I: Menstruation (Day 1-7):
 Break down of the endometrium
 Average blood loss is about ¼ to ½ of a cup.
 Phase II: Proliferation (Days 7-15):
 Endometrium replaces itself and increases in size due to the increase in estrogen secretion.
 Estrogen, FSH and LH, help ovulation take place during this phase (around day 14).
 Phase III: Secretion (Days 16-28):
 Endometrium doubles in thickness making the uterus ready to accept a fertilized ovum.
Progesterone released.
A pair of glands (testicles) that
produce sperm and testosterone.
A coiled tube where sperm matures
(if stretched out, this tube would be
20 ft long!!)
Skin covered sack, it contracts and
relaxes to move the testes closer or
farther away from the body to
regulate their temperature
Sperm travel into this tube and are
stored here until they leave the body
during ejaculation or are reabsorbed
Tiny organ(s) that also secretes fluid
to nourish the sperm
Secretes fluid that also nourishes and
protects the sperm
Sperm and urine leave the body
through this tube which passes
through the penis
The external male sex organ.
Comprised of spongy tissue, muscles,
veins, fibrous tissue, and the urethra.
