What is the main purpose of the kidney?

Answer 1

The kidneys are very important to your urinary system. It is responsible for cleaning your blood from waste products and also dead red and white blood cells. Then it turns it in to urine and poo and then is removed.

It maintains the amount of water in the body.

Answer 2

Several contributors have put together this well thought out answer.

The urinary system has three major functions:

(1) excretion: the removal of organic waste from body fluids.

(2) elimination: the discharge of these waste into the outside.

(3) homeostatic regulation of the volume and solutes of blood plasma.

There are two kidneys, the organs that produce urine which is a fluid containing water, ions, and small soluble compounds.

In addition to removing waste products generated by body cells the kidneys have several other essential homeostatic functions:

1. Regulating blood volume and blood pressure, by adjusting the volume of water lost in urine, releasing erythropoietin, and releasing renin.

2. Regulating plasma concentrations of sodium, potassium, chloride, and other ions.

3. Controlling calcium ion levels through the synthesis of calcitriol.

4. Helping to stabilize blood pH, by controlling the loss of hydrogen ions and bicarbonate ions.

5. Conserving valuable nutrients while excreting organic waste products, mainly nitrogenous wastes such as urea and uric acid.

6. Assisting the liver in detoxifying poisons.

Your kidneys receive 20-25 percent of your total cardiac output. Normally about 1200 ml of blood flows through the kidneys each minute.

Lastly:

The sympathetic innervation:

(1) adjusts rates of urine formation by changing blood flow and blood pressure in the kidney.

(2) stimulates the release of renin, which restricts losses of water and salt in the urine through reabsorption at the nephron.

The main purpose of the kidneys is to separate urea, mineral salts, toxins, and other waste products from the blood. In addition, the kidneys also conserve water, salts, and electrolytes.

At least one kidney must function properly for life to be maintained.

Simply put, the kidneys filter the bloodstream in order to get all of the toxins out of your body, and also regulate certain body fluids.

Kidneys are vital organs that function to keep the blood clean and maintain chemical balance within. They process blood to extract waste products and extra water. These by products become urine to be ultimately excreted from the body.

The kidney serves many important functions, including:

1. Filtering out wastes to be excreted in the urine.
2. Regulating blood pressure via both urinary excretion of wastes and initiating the rein-angiotensen hormone regulatory system
3. Regulating an acid-base balance via the bicarbonate system
4. Stimulating red blood cell production via the release of the hormone erythropoietin.

The kidney is there to filter our blood entirelyof molecules and small things we don't particularly need in our blood supply.

Urine is actually what our kidneys have filtered.

Interesting fact: We have two kidneys to get the filtering done well. Well enough to filter our blood entirely - several times every five minutes.

Answer 3

Kidneys filter the blood; they separate and eject the waste, and reabsorb what the body still needs. That way they control, regulate the concentration of salts/electrolytes in the body, and also the volume of fluid. If the kidneys fail to function, kidney dialysis keeps you alive.

Answer 4

It maintains the amount of water in the body - Apex

Answer 5

Filtration of the blood and excretion of wastes that are in the blood due to bodily processes.

Answer 6

primary function of kidney is to maintain proper balance of various substances such as water, sodium, potassium, magnesium, glucose, urea, bicarbonate and many other chemicals.
