The circulatory system, also called the cardiovascular system or the vascular system, is an organ system that permits blood to circulate and transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases, stabilize temperature and pH, and maintain homeostasis.
The role of the circulatory system is to transport oxygen and other necessary nutrients all throughout the body. The main part of the circulatory system is the heart. The heart is the organ responsible for pumping blood throughout the body. This system has three types of blood vessels: The largest are arteries which go away from the heart. Next are veins which lead to the heart and are the second largest vessel.
