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.he 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 systemic circulation is a major portion of the circulatory system. The network of veins, arteries and blood vessels transports oxygenated blood from the heart, delivers oxygen and nutrients to the body's cells and then returns deoxygenated blood back to the heart. The system of blood vessels in the human body measure about 60,000 miles (96,560 kilometers). Arteries carry oxygen-rich blood from the heart through the body. Veins carry oxygen-poor blood back to the heart. The superior vena cava carries oxygen-poor blood into the heart.
