ANATOMY

Detailed explanation-1: -The kidneys regulate circulatory volume by controlling sodium and water balance, thus maintaining extracellular fluid volume (ECFV) homeostasis.

Detailed explanation-2: -The homeostatic functions of the kidney include the control of the balance of water, sodium, chloride, potassium, calcium, magnesium, hydrogen ions, and phosphate.

Detailed explanation-3: -The kidneys are essential for cleansing the blood and eliminating urine waste from the body. They also have other important functions that maintain homeostasis in the body including regulating acid-base balance, the concentration of electrolytes, controlling blood pressure, and secreting hormones.

Detailed explanation-4: -The kidneys serve several essential regulatory roles. They are essential in the regulation of electrolytes, maintenance of acid-base balance, and regulation of blood pressure. They serve the body by filtering blood to remove wastes that are diverted to the urinary bladder for excretion.

Detailed explanation-5: -It acts as a buffer by combining with secreted hydrogen ions to form dihydrogen phosphate H2PO4-which is then peed out in the urine. All right, as a quick recap, the kidneys help maintain pH balance of the blood.
