What are Kidneys Functions?

Hello 123


Kidneys are two bean-shaped organs that remove excess fluid and waste from the body through urine. Each kidney is about the size of a fist and they are located against the back muscles in the upper abdominal area on either side of the spine. Kidneys also produce hormones that perform necessary functions in the body, such as:
● Produce red blood cells
● Regulate blood pressure
● Keep bones strong and health

How do Kidneys function?

Kidneys are made up of about a million filtering units called nephrons. Each nephron consists of tiny blood vessels called glomerulus, and a tubule. Blood containing waste enters the kidney through the renal artery and into the glomerulus which filters the blood, and the tubule removes waste and excess fluid, and returns the nutrients back to the blood. The removed waste and excess fluid becomes urine and go to bladder to be released by the body, while the clean blood leaves the kidney through the renal vein. Kidneys filter and clean almost 200 litres of blood every day.

Why are Kidneys important?

The Kidneys are important because they perform 3 vital functions which are necessary for the body:

1.  Maintain water in the body

Our bodies need a certain amount of water to work properly. Too little water or too much water can lead to conditions that may severely affect the body and cause serious problems Kidneys help to remove excess water, or retain water when needed.

2.  Remove waste products and balance the body’s minerals

Urea and other waste products are produced in the body when it digests the food that we eat, such as meat. The kidneys removes this waste.

Minerals, such as sodium, calcium, potassium and phosphate, must be kept at a balance for the body to function. We get these minerals from the foods we eat, but too much of these minerals can cause other serious health problems. The kidneys keep these minerals in balance by removing the excess through the urine.


3.  Hormone Production

The kidneys produce hormones in the body that help in certain crucial functions like regulate blood pressure and produce red blood cells.
