Document Summary
Collections of lymph on lining of sites. Lymph nodes, thymus, spleen, red bone marrow. Participate in immune responses to protect against foreign pathogens. Lymphatic capillaries collect interstitial fluid (lymph) from tissue spaces, and merge into larger lymph vessels. Lymph vessels ultimately merge into right lymphatic duct and thoracic duct. Ducts return fluid to the blood circulation at the subclavian veins. Lymph circulates through lymph nodes scattered through the body. Collect interstitial fluid (lymph) from tissue spaces. Penetrate tissue of body where blood capillaries are present. Merge into larger vessels (right lymphatic duct) Lymph vessels merge into right lymphatic and thoracic ducts. Ducts return fluid to the blood circulation at subclavian veins. Lymph into nodes via afferent lymphatic vessels. Lymph exits through 1-3 efferent lymphatic vessels. Sites where cells of immune system are generated and mature. Ex: red bone marrows (all form elements of blood) Mature cells of the immune system aggregate and initiate a specific immune response.
