The role of this system
The role of the excretory system is to eliminate liquid waste
from the body.
Without this system the body would build up too much toxic
waste to allow it to function properly.
The major organs of the excretory system are kidneys,
bladder, ureter and urethra.
Kidney: Filters waste from the blood.
Bladder: Stores liquid waste.
Ureter: Carries waste from the kidney to the bladder.
Urethra: Carries urine from the bladder out of the
body.
How do the major
organs work together?
The kidneys filter waste from the blood through tiny filtering units called
nephrons.
The bladder is where urine is stored.
The ureter is where the urine passes through to drain into the bladder.
The urethra is the last part of this system, it is where the urine passes
through to exit the body.
The excretory system is connected to the
circulatory system and endocrine system.
first the blood that circulates through
the body passes through one of the two
kidneys. Urea, uric acid, and water are
removed from the blood and most of the
water is put back into the system.
Second the endocrine system is the major
controller of the excretory system. As
levels of compounds and fluids are
monitored, kidney function must be
constantly altered to provide the best
internal environment for your cells. If
you drink too much water, hormones are
released that allow for more urine
production. If you are dehydrated, less
urine will be produced.

Levels of organization
The kidneys are organs, they are
made up of many types of tissues
and cells.
One of the types of tissues is epithelial
tissue, it surrounds the kidneys.
The epithelial tissue is made up of
many epithelial cells.
Uremia is a disease that affects excretion. Uremia
is when urea and other waste products build up in
the body because the kidneys are unable to
eliminate them. These substances can become
poisonous (toxic) to the body if they reach high
levels.
Uremia can result from any disorder that impairs
the functioning of the kidneys or that hinders the
excretion of urine from the body. The ultimate
treatment for uremia is dialysis and it is not
treatable by other medical means.
Kidney Stones is when uric acid forms crystals
that bundle up in the kidneys, this prevents the
kidneys from functioning correctly and causes
pain. Medical evidence suggests that drinking too
few fluids can increase the risk for forming kidney
stones because dehydration concentrates the
minerals in the urine and makes crystal formation
easier. But unfortunately there is no cure for
kidney stones
How to maintain a healthy
system
To keep a healthy urinary tract you should be sure to drink
water when you are thirsty. This helps keep urine flowing
normally and it helps avoid blockages in the urinary tract.
Also don’t eat too much salt. Excess salt keeps the
salt/mineral/water in your kidneys off balance. Too much
salt is also known to cause kidney stones.
A urologist is a profession that works with the excretory
system. Urology is the medical and surgical specialty that
focuses on the urinary tracts of males and females. A
urologist helps women with bladder infections or
incontinence, or men with impotence or problems
passing urine.
A urologist usually works from within a hospital. Often
the patient will have a choice between several hospitals
and /or several urologists, although most general
practitioners deal with only one or two urologists, with
whom he/she is familiar.
A Nephrologist is a doctor that deals with the excretory
system. These medical professionals specialize in
diagnosing and managing the function of diseases and
other complications associated with the kidneys.
Nephrologists often spend part of their day in their office,
interviewing and examining patients, and then spend
another part of the day visiting other patients in the
hospital and reviewing their progress. They also spend
time meeting with doctors who have referred patients to
them, discussing the patients' progress
6 Interesting or Strange Facts

2) The average adult bladder can hold 16-24 ounces of urine.
3) One kidney measures approximately 4 inches.
4) The average person passes approximately
1.5 to 2 liters of urine a day
5) In a healthy adult almost 440 gallons of blood passes through the
kidneys every day.
6)Ancient Rome used urine as a bleaching agent for cleaning
clothes.
