Answer 1

to throw the liquid waste out side the body

Answer 2

Hey, here is your answer -

The kidneys are made up of millions of the microscopic units called neprons. They are surrounded by a network of blood capillaries. Blood which enters the kidney through the renal artery contains unwanted waste substances as well as some useful substances. The nephrons remove the waste substances and convert it into urine. They also re absorb certain useful substances that are needed by the body and put it back into the blood. The blood that finally leaves the kidney is pure, devoid of all wastes and contains the right amount of water and other useful substances required by the body. The urine that is formed in the kidneys is sent to the ureters for its further temporary collection in the urinary bladder. When the blade is full, the urine is expelled through the urethra.
