Do Now: Can you name some parts of the excretory system?
Warm Up ( Think About)
How does our body parts depend on each other? And Does certain
parts of our body affect other parts?
Think over with a partner for 2 mins.
The excretory system is responsible for the excretion
of nitrogenous wastes in form of urea, and the
reabsorption of water and vital minerals to maintain
balance in the human body. The main function of the
excretory system, also referred to as the urinary
system, is to maintain a proper balance of body
fluids through the excretion of waste products.
Flash Question :
What system is the Excretory
system connected with ?

The Kidneys are paired organs responsible for urine formation
3 Major Parts of the Kidneys are :
Cortex- contain the fluid filtering mechanism
 Medulla- contains collecting ducts leading to renal pelvis
 Renal Pelvis- funnel shaped, collecting area that collects urine that then
drains out of the Ureter .

Ureter are long tubes leading from the Kidney to the Bladder
 The Bladder stores urine from the Ureters. The bladder is covered
by a smooth muscle
 The Urethra is a tube that take urine out the body with the help of
the Urethral Sphincter.

Nephritis
Any type of kidney
inflammation,
affects children and
teenagers far more
than adults
Nephritis can be
caused by infection,
but mostly by
autoimmune
disorders

disease caused by a
defect in the
glomeruli.

Kidney Stones
A kidney stone is a
solid mass made up
of tiny crystals. One
or more stones can
be in the kidney or
ureter at the same
time.

Description Causes
Symptoms
Treatment
Ureterocele
swelling of one of
ureters (tubes),
usually occurs in the
lower part of the
tube. The urine
released from the
kidney may build up
in the ureter and
form a sac like
structure. This
swollen area may
prevent urine’s flow
to the bladder.
The swollen area
prevents urine from
moving freely into
the bladder. The
urine collects in the
ureter and stretches
its walls, blowing it
up like a water
balloon.

Urinating
Foul-Smell Urine

Draining of the
Ureter
Vesicoureteral
Reflux
common in children,
but may carry in
adulthood. Urine
would flow back to
ureters from the
bladder; that could
lead to infection.
The cause is due to
the malfunctioned
valve between the
bladder and ureters.
This defect occurs
before birth.

Most of the Excretory Diseases occur due to the malfunction
of these structures. Some Excretory diseases can affect
certain structures in the system but it can also cause
complication to he rest of the system if left untreated.
