The diagram shows an outline of the
male reproductive system. What number indicates the
urethra?
This question is asking us about
the male reproductive system. The purpose of this system is to
deliver semen, which contains sperm, to the female reproductive system using the
penis. A sperm cell can then combine with
an egg cell that’s made by the female reproductive system, to make a fertilized
egg. This fertilized egg can then make a
baby, which can develop in the female reproductive system. To answer our question and see
where the urethra is, let’s go through this provided diagram and discuss how sperm
can be released through the penis.
Sperm is produced in the testes, or
testis as singular. These are sometimes called the
testicles. Sperm are sensitive to high
temperatures, so the testes are kept outside the body in a sac of skin called the
scrotum. The sperm that are made in the
testes are stored in a region called the epididymis. When the male is sexually aroused,
the sperm can travel from the epididymis through a tube called the vas deferens. The sperm can then mix with fluids
from different glands to form semen. One of these glands is called the
seminal vesicles. Another gland that adds fluid to
make semen is the prostate gland.
Now that semen is prepared, it can
be ejaculated, or ejected, from a tube called the urethra. During sexual intercourse, the
ejaculated semen can enter the female reproductive system where a sperm cell in the
semen can fertilize an egg cell. The last number in our diagram
indicates the bladder. In males, the urethra is also the
tube that is used to expel urine from the bladder.
Getting back to our question, the
urethra is indicated by number 5.
