Kidney
Function and Location
The kidneys, a part of the urinary system, are a pair of bean
shaped organs in the back of abdomen. They clean the body of
excess water, salt and waste products. As blood circulates through
the kidneys, it passes through more than a million tiny filtering
units within them. These filters produce a liquid waste, urine.
Urine flows from the kidneys through a pair of thin tubes, the
ureters, to the bladder, where it is stored until a person urinates.
During urination, the urine leaves the body by passing from the
bladder through another tube, the urethra, which is open at one
end.
The kidneys also produce important hormones that help regulate
blood pressure, form bone, and control red blood cell production
in bones.
