regulates blood volume and pressure, stimulates red blood cell formation, and controls fluid, electrolyte, and acid-base balance
omeli [17]

The Circulatory  system regulates blood volume and pressure, stimulates red blood cell formation, and controls fluid, electrolyte, and acid-base balance.

What is Circulatory  system?

To obtain oxygen into the blood, the circulatory system (cardiovascular system) pumps blood from the heart to the lungs. The remainder of the body receives oxygenated blood from the heart via arteries. Oxygen-depleted blood is returned to the heart by veins to restart circulation.

The human body is a tremendously intricate structure with numerous organ systems, including the brain, which regulates all bodily functions, lungs, which assist in gas exchange, and kidneys, which filter out waste products. However, the circulatory system controls all of these since blood is a fluid that keeps the body free of any materials that are not necessary for the body.
