Document Summary

Up until now, we have learned specific tissues which are the building blocks of larger structures. The first one we will learn about is blood vessels. The circulatory system consists of the heart, whose function is to pump blood, and the vascular system, containing afferent and efferent blood vessels. Efferent vessels are the arteries, which leave the heart and bring oxygen and nutrients to all tissues through a capillary network. Afferent vessels are veins, which come back to the heart, carrying in the carbon dioxide and waste products from all tissues through the convergence of the capillary system larger vessels. The lymphatic vascular system is an anastomic network of vessels closely related to the vascular system. Lymphatic vessels behind as blind (one ended) capillaries which converge into lymphatic vessels, and then into lymphatic ducts. These lymphatic ducts drain into large veins. These vessels contain lymph which is plasma enriches in immunoglobulins and lymphocytes produced by lymphatic organs.
