The excretory system regulates blood volume by doing what?
A
making blood cells
B
breaking down food
C
eliminating excess water
D
filtering blood
Explanation: 

Detailed explanation-1: -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-2: -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-3: -One way the the kidneys can directly control the volume of bodily fluids is by the amount of water excreted in the urine. Either the kidneys can conserve water by producing urine that is concentrated relative to plasma, or they can rid the body of excess water by producing urine that is dilute relative to plasma.

Detailed explanation-4: -The renal system, and more specifically the kidney, is primarily responsible for regulating blood volume. The kidney’s primary function is to modify the solutes and water content of the blood through filtration, reabsorption, and secretion.

Detailed explanation-5: -Urine volume and concentration is regulated through the same processes that regulate blood volume. Antidiuretic hormone (ADH)-produced by the posterior pituitary gland-increases the amount of water reabsorbed in the distal convoluted tubule and collecting duct.
