THE URINARY SYSTEM
Thousands of metabolic processes in myriad
body cells produce hundreds of waste
products.
The urinary system removes them by filtering
and cleansing the blood as it passes through
the kidneys.
Another vital function is the regulation of the
volume, acidity, salinity, concentration, and
chemical composition of blood, lymph, and
other body fluids.
Under hormonal control, the kidneys
continually monitor what they release into the
urine to maintain a healthy chemical balance.
Disorders of the system can be subtle, so
urination-related symptoms should be
promptly reported.
,The urinary system is composed of a pair of
kidneys, a pair of ureters, a bladder, and a
urethra.
These components together carry out the
urinary system’s function of regulating the
volume and composition of body fluids,
removing waste products from the blood, and
expelling the waste and excess water from the
body in the form of urine.
The two kidneys are reddish organs resembling
beans in shape that are situated on either side
of the abdomen just above the waist and
towards the back of the body.
The kidneys contain microscopic filtering units
that remove waste, unwanted minerals, and
excess water from the blood as urine.
Each kidney is connected to the bladder by a
long tube called a ureter, which transports urine
away.
