What is the function of kidneys?

The kidneys are the main excretory organs responsible for filtering blood and removing waste products from the body.

Their primary function is to remove substances such as urea, excess salts, and extra water from the blood to form urine.

Kidneys also help maintain the body’s internal balance by regulating water levels, salt concentration, and pH balance.

In addition, they play a role in controlling blood pressure and producing certain hormones involved in red blood cell formation and calcium balance.

By continuously filtering blood and removing wastes, the kidneys help keep the body healthy and functioning properly.
