The circulatory system is often seen to comprise both the cardiovascular system, which distributes blood, and the lymphatic system, which circulates lymph. These are two separate systems. The passage of lymph for example takes a lot longer than that of blood. Blood is a fluid consisting of plasma, red blood cells, white blood cells, and platelets that is circulated by the heart through the vertebrate vascular system, carrying oxygen and nutrients to and waste materials away from all body tissues.
The circulatory system transports nutrients and blood cells to and from cells throughout the body. Blood is oxygenated in the lungs then sent back to the heart to be pumped to the rest of the body in blood vessels. The types of blood vessels include veins, arteries and capillaries. Veins carry blood to the heart while arteries carry blood away from the heart. Oxygen diffuses into the cells directly from the capillaries.
