Question

Kidneys collect the fluid portion of blood & do many functions. What are they?? Give 5 examples.

Answer 1

The kidneys perform a wide range of vital functions in the healthy body, such as:
Removing wastes and water from the blood
Balancing chemicals in your body
Helping control blood pressure by removing excess salt
Helping to produce red blood cells
Producing vitamin D, which keeps the bones strong and healthy

In addition to removing wastes, the kidneys release three important hormones:

erythropoietin, or EPO, which stimulates the bone marrow to make red blood cells
renin, which regulates blood pressure
calcitriol, the active form of vitamin D, which helps maintain calcium for bones and for normal chemical balance in the body.
