PATHOLOGY

Detailed explanation-1: -The renal system regulates blood pressure by altering the amount of water held in the blood (blood volume). The renal system regulates blood pH by excreting and reabsorbing hydronium ions and bicarbonate. The renal system does not play a direct role in regulating blood temperature.

Detailed explanation-2: -Your urinary system, also called the renal system or urinary tract, removes waste from your blood in the form of urine. It also helps regulate your blood volume and pressure, and controls the level of chemicals and salts (electrolytes) in your body’s cells and blood.

Detailed explanation-3: -The kidneys regulate circulatory volume by controlling sodium and water balance, thus maintaining extracellular fluid volume (ECFV) homeostasis. Simply put, an increase in sodium and water consumption leads to an increase in ECFV, which in turn increases blood volume.

Detailed explanation-4: -Hormones The kidneys secrete a number of hormones, which are important for normal functioning of the body. One such hormone is renin, which keeps blood pressure normal. If blood pressure falls, renin is secreted by the kidneys to constrict the small blood vessels, thereby increasing blood pressure.
