The circulatory system is made up of the heart and blood vessels. There are three types of blood vessels: arteries, veins, and capillaries. Arterial blood flows through the arteries, that is, blood that is enriched with oxygen. Venous blood flows in the veins. It is formed after arterial blood enters the cells and loses oxygen. The venous blood is darker. An important part of the circulatory system is blood. It consists of plasma, red blood cells, platelets and leukocytes. Red blood cells are responsible for the transfer of oxygen.
