Explanation The various anatomic structures present in lymphatic systems are: 1. Lymphatic vessels: Lymphatic capillaries combine together to form large lymphatic vessels. Lymphatic vessels are made up of three tunics–intima, media and external layer and also have valves in their lumen. Lymph from lymphatic vessels is transported to lymphatic trunks present on both left and right regions of the body. Lymph is then finally drained into the right lymphatic duct and thoracic ducts before it is released into the blood. 2. Primary lymphatic structures: The primary lymphatic structures are responsible for the formation of lymphocytes and maturation of lymphocyte. It includes thymus and red bone marrow. Red bone marrow is found within the trabeculae of spongy bones formation of formed elements of blood (erythrocyte, leukocyte, and platelets). The thymus is formed of two lobes that are fused and surrounded by a tissue called capsule. Trabeculae which are the capsule’s fibrous extensions divide thymus lobes into outer cortex lobule and inner medulla lobule...
