Today’s Presentation
Objectives:




Explore the anatomy and functions of the male
genito-urinary system, in an easy-to-understand
manner.
Talk about problems and diseases related to the
prostate.
Discuss a variety of strategies available to prevent
and fight problems with the prostate gland.
Questions and Answers regarding prostate cancer
from our perspective of “professional survivors”.
The grapefruit below represents the
urinary bladder:



The drinking straws
represent the ureters, two
tubes that connect each
kidney to the bladder.
The kidneys clean the blood
and filter waste from it This
process produces urine.
Urine flows from the kidneys
through the ureters to the
bladder, where it is stored
until a person urinates.
Note the stem of the
grapefruit is at the bottom, to
represent the valve or
sphincter that opens and
closes to control urination.

This lemon, pierced by another drinking
straw, represents the prostate gland:

A normal prostate is the size
of a walnut
All glands produce specialized
secretions that serve specific
functions for the body.
 The prostate is located directly
underneath the bladder.
 The prostate gland produces a
white, thick fluid, whose only
function is to provide food and
transportation for the sperm.
The sperm is produced in the
testicles.
 The drinking straw going
through the middle of the
prostate is the urethra, which
discharges either urine or
semen. The urethra is
connected to the sphincter
between the bladder and the
prostate.
Bladder, ureters; prostate gland and urethra are located in
front of the abdomen.

corpora cavernosa and the
glans.
The urethra is located at the
bottom of the penis and
carries urine or, semen
during sexual activity.
Two chambers named
corpora cavernosa are
located at the top on both
sides of the penis. When
sexually aroused, each fills
with blood from the arteries,
causing an erection.
The glans is the end portion
of the penis, is very
sensitive, and provides
sexual pleasure.

Inside each testicle is an
epididymus “the nut” where
millions of sperm cells are
created.
The sperm cells travel through
two tubes named vas deferens
to the seminal vesicles, where
it is stored.
The seminal vesicles will have
spasms during sexual activity,
causing the sperm to mix with
the white fluid in the prostate.
The resulting mixture is called
the semen.
The semen is expelled from the
body, (ejaculation) and
produces the intense sexual
pleasure of the orgasm.

Congratulations! You have now
completed your “Anatomy for
Dummies” course.
(give yourselves a pat on the back)
In order to graduate, you will now have
a test to identify the male anatomy
with real anatomical models:
Identify the bladder, ureters, prostate gland,
sphincter and urethra.
Rear view: Identify the bladder, prostate, vas deferens and
seminal vesicles.
Graduates, please come forward to receive your wellearned diploma from the “Anatomy for Dummies”
University!
Next we will look at the problems and diseases of the
prostate gland.
