Human Reproductive System

Human Reproductive System

Multiple Choice

The process of the crossing-over of genes occurs during this:

• meiosis I

• meiosis II

• telophase

• spermiogenesis

Female Reproductive System

Label all the parts of female reproductive system on your notebook.

Copy the function of each structure.

Cervix

The cervix is the lower,
narrow portion of the
uterus where it joins
with the top end of the
vagina. The cervix has
an opening to allow
sperm and menstrual
fluid to move through.

Vagina

The vagina is a hollow
muscular organ that
joins the cervix (the
lower part of uterus) to
the outside of the body.
The vaginal walls are
lined in a mucus
membrane for
protection and to keep
it moist.

Uterus

The uterus, or womb, is
a hollow, pear-shaped
organ where the fetus
develops during the
gestation. One end, the
cervix, opens into the
vagina, while the other
is connected to one or
both fallopian tubes.

Fallopian Tubes (Oviducts)

In a woman's body, the
fallopian tubes (also
known as the oviducts)
allow passage of the egg
from the ovary to the
uterus. This is where
fertilization occurs.

Ovaries

The ovaries produce
the female gonads, or
eggs. All eggs are
present at birth.
Ovaries also produce
estrogen which
maintains secondary
sexual characteristics.

Multiple Choice

What is the main function of the female reproductive system?​ ​ ​ ​ ​ ​ ​

• To accept male gametes (sperm) and to nourish and develop offspring

• To deliver male gametes (sperm)

• To produce male sex hormones

• To produce gametes (sperm) by meiosis

Male Reproductive System

Label all the parts of male reproductive system on your notebook.

Copy the function of each structure.

Seminal Vesicle

Seminal vesicles are
sac-like structures
attached to the vas
deferens at one side
of the bladder. They
produce a sticky,
yellowish fluid that
provides sperm cells with energy. This is semen.

Epididymis

The epididymis is a
whitish mass of
tightly coiled tubes
cupped against the
testicles. It acts as
a maturation and
storage place for
sperm before they pass into the vas deferens.

Prostate Gland

The prostate gland
surrounds the
ejaculatory ducts at the
base of the urethra, just
below the bladder. The
prostate gland is
responsible for the production of semen, a liquid
mixture of sperm cells, prostate fluid and seminal
fluid.

Urethra

The urethra is a tube
that connects the
urinary bladder to
the genitals for the
removal of fluids
from the body. In
males, the urethra
travels through the penis, and carries semen as well
as urine.

Vas Deferens

The vas
deferens, also
known as the
sperm duct, is a
thin tube that
starts from the epididymis to the
urethra.

Scrotum

The scrotum is a pouch-
like structure that hangs
behind the penis. It
holds and protects the
testes. It also contains
numerous nerves and
blood vessels.

Penis

The penis is
the male sex
organ. It
releases the
sperm from
the body.

Testis (Testicle)

The testes are
the male
gonads. They
produce
sperm and
hormones, mainly testosterone.

Multiple Choice

This gland secretes a thick mucus like substance that contains fructose to nourish sperm cells, fibrinogen to cause semen to clot and prostaglandins that cause uterine contractions:

• prostate

• epididymis

• seminal vesicle

• testis
