“Circulatory System in a Nutshell”

Blood vessels make up the circulatory system, which transports blood to and from the heart. Blood is transported from the heart by arteries and returned to it via veins. The circulatory system eliminates waste materials like carbon dioxide from the body and delivers hormones, nutrients, and oxygen to the cells. To keep things moving in the proper direction, these roads only go in one direction.
