THE
RENAL
(URINARY OR EXCRETORY)
SYSTEM
,Introduction
The body maintains the homeostasis of several important internal conditions by
controlling the excretion of substances out of the body through the renal system
function. Urine is formed while normal blood compositions are reabsorbed into the
body through active and passive transport, and ammonia in the form of uric acid is
excreted as waste. This process also, has a significant role in the maintenance of
electrolytes balances in the body.
Definition of the Renal System
The renal system is also called the urinary or excretory system of the body. This is
because, some of its functions include the formation of urine and removal
(excretion) of waste products from the blood and their elimination from the body to
the outside.
The Components of the Renal System
The urinary system consists of:
• Two (2) Kidneys
• Two (2) Ureters
• One (1) Urinary bladder
, • One (1) Urethra
