The main purpose of the blank system is to distribute blood throughout the body

Answer 1

The main purpose of the circulatory system is to distribute oxygen, nutrients, hormones, and other molecules throughout the body, as well as remove waste products and regulate body temperature. This is accomplished through the pumping action of the heart, which circulates blood through a network of blood vessels, including arteries, veins, and capillaries. Additionally, the circulatory system plays a vital role in the immune response, helping to transport immune cells to sites of infection and injury.
