The study of the properties of the blood flow is called hemorheology. The circulatory system is often seen to comprise two separate systems: the cardiovascular system, which distributes blood, and the lymphatic system, which circulates lymph. The passage of lymph for example takes much 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.
(lÄ­m-fÄtâ²Ä­k) A network of vessels, tissues, and organs in vertebrate animals that helps the body regulate fluid balance and fight against disease. The vessels of the lymphatic system drain excess fluid (called lymph) from the tissues and return it to the circulating blood. Lymphocytes circulate throughout the lymphatic system.
