MICROANATOMY

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 maintain homeostasis by controlling the amount of water, ions, and other substances in the blood.

Detailed explanation-3: -They help control the chemical balance of the blood and regulate the body’s level of sodium, potassium and calcium. The kidneys remove waste products and excess water from the body and so help to regulate blood pressure.

Detailed explanation-4: -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-5: -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.
