Circulatory System. This system is made up of the heart, blood, blood vessels, and lymphatics. It is the bodyâs delivery system, concerned with circulating blood to deliver oxygen and nutrients to every part of the body.
The Human circulatory system is an organ system that is mainly concerned with transportation of nutrients, gases, blood cells and hormones throughout the body, through a network of blood vessels. It is also the main cooling as well as transportation system of the body. The RBCs carry nutrients and oxygen to the cells while the white blood cells in the circulatory system act as cleaners and start functioning whenever we are exposed to cold, infection or cut. The main components of circulatory systems are arteries and veins.
