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 kidneys regulate the fluid and electrolyte balance of the body by continually filtering the blood. This is vital to maintain a constant extracellular fluid volume and composition.

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.

Detailed explanation-4: -If a person does not drink enough, the body fluids become more concentrated and, as a result, the kidneys excrete a more concentrated urine. If an excess of fluid is drunk, the body fluids become more diluted, and the kidneys excrete a more dilute urine, getting rid of the excess that has been taken in.

Detailed explanation-5: -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.
