5. 1 describe the structure and explain the main funcions of the vessels and organs of the lymphaic system. Lymphaic capillaries collecing vessels trunks ducts. Right lymphaic duct drains from right thoracic cavity. Lymphaic trunk: drains lymph from speciic body areas. The right lymphatic duct drains the right head and neck region. Macrophages: phagocyize foreign substances, and activate t cells. Houses and provides a proliferaion site for lymphocytes, furnishes a nice surveillance point for lymphocytes and macrophages! Composed of reicular connecive issue: in all lymphoid organs except the thymus, also in lamina propria of mucous membranes, lymphocytes make temporary stopovers in between patrolling the body. Discrete, encapsulated collecions of difuse lymphoid issue + follicles. ~ 2. 5 cm long, divided into compartments by trabeculae. Cortex: follicle with germinal centres (b cells divide here) Medulla: medullary cords and large lymph sinuses. One way low of traic in each lymph node.
