THE MAJOR FUNCTIONS OF THE KIDNEYS

maintain the balance of the water and the levels of the chemical constituents (electrolytes, hormones, blood sugar, ect) in the fluids of the body

The following substances are bieng produce by the kidneys:
REnin- An enzyme that regulate blood pressure
ACTIVE FORM OF VITAMIN D- Helps maintain calcium absorptuin for bone formation, at the same time maintains calcium balance in the body
ERYTHROPOIETIN- a HORMONE THAT STIMULATES THE BONE MARROW TO MAKE RED BLOOD CELLS

ELIMINATE CHEMICAL WASTES FROM THE BLOOD

From time to time our blood accumulates substances that have t be eliminated. these include the end products of metabolism such as urea, creatinine, uric acid and urates.In addition many other substances such as ions of sodium, potassium, chloride, and hydrogen tend to accumulate in the blood in excess quatities. It is then the function of our kidneys to clear these excesses.

HELP CONTROL THE ACID-BASE BALANCE OF THE BLOOD

when we speak of the regulation of acid-base balance, we generally maen the regulation of hydrogenion concentration in the body fluids. when the hydrogen ion concentration deviates from the normal, the kidneys will form either an acidic or alkaline urine.in this way the kidneys will help readjust the hydrogen ion concentration in order to maintain its balance to a normal level
