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: -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.

Detailed explanation-3: -The renal system consists of the kidney, ureters, and the urethra. The overall function of the system filters approximately 200 liters of fluid a day from renal blood flow which allows for toxins, metabolic waste products, and excess ion to be excreted while keeping essential substances in the blood.
