MICROANATOMY

Detailed explanation-1: -The kidneys maintain homeostasis by controlling the amount of water, ions, and other substances in the blood. Kidneys also secrete hormones that have other homeostatic functions.

Detailed explanation-2: -Water homeostasis is achieved by regulation of water intake and water loss by the kidneys. The former is achieved by sensations of thirst that motivate water acquisition, whereas the latter is regulated by the antidiuretic action of vasopressin.

Detailed explanation-3: -Your kidneys remove wastes and extra fluid from your body. Your kidneys also remove acid that is produced by the cells of your body and maintain a healthy balance of water, salts, and minerals-such as sodium, calcium, phosphorus, and potassium-in your blood.
