Final answer:
The lymphatic system is made up of lymph, lymph vessels, and lymphatic organs like the bone marrow, thymus, spleen, and tonsils.
Step-by-step explanation:
The lymphatic system consists of lymph, lymph vessels, and lymphatic organs. The lymph itself is a fluid that bathes tissues and organs, which contains protective white blood cells and is devoid of erythrocytes (red blood cells). Lymphatic vessels form a network that operates alongside the cardiovascular system, transporting the lymph from tissues throughout the body, eventually draining back into the bloodstream. As it circulates, lymph is filtered through lymph nodes, which remove pathogens and are aided by lymphocytes. Lymphatic organs include the bone marrow, thymus, spleen, and tonsils, playing critical roles in the production, maturation, and housing of lymphocytes.
