Overview: Lymphatic drainage

Tissue fluid, monitored by MALT (diffuse and nodular lymphoid tissues), passes into lymphatic capillaries where it is now called lymph. Lymph contains antigens as well as immune cells exiting the tissues. Lymphatic capillaries anastomose to form larger lymph vessels that carry lymph to lymph nodes, where it is further monitored for the presence of antigens. Lymph eventually drains into the blood vascular system. 600x, 400x

Lymph capillaries > <p>Lymph capillaries begin as blind-ended tubes in the lamina propria of peripheral organs and resemble blood capillaries, formed by a single layer of endothelial cells. Lymphatic capillaries come together to form larger lymph vessels that acquire additional layers of smooth muscle and connective tissue. Lymph vessels possess valves, flaps formed by the inner lining, to prevent backflow of the fluid. Lymph vessels drain into lymph nodes located along their length.</p>
