Answer 2

The major functions performed by kidneys are:

(i) Eliminating excess water from the body

(osmoregulation) and nitrogenous wastes (urea and

uric acid) from blood in the form of urine. Urea is

a result of nitrogen metabolism occurring in the liver.

(ii) Sustaining the constant concentration of blood

plasma.

(iii) Regulating the pH of the blood.

(iv) Homeostasis.

Each kidney is made up of thousands of tiny filtration units or tubules, they are called nephrons.
