IMMUNOLOGY

Detailed explanation-1: -The lymphatic system is a network of delicate tubes throughout the body. It drains fluid (called lymph) that has leaked from the blood vessels into the tissues and empties it back into the bloodstream via the lymph nodes. The main roles of the lymphatic system include: managing the fluid levels in the body.

Detailed explanation-2: -Primary lymphoid organs: These organs include the bone marrow and the thymus. They create special immune system cells called lymphocytes. Secondary lymphoid organs: These organs include the lymph nodes, the spleen, the tonsils and certain tissue in various mucous membrane layers in the body (for instance in the bowel).

Detailed explanation-3: -The Lymphatic System Consists of Two Main Parts: The Vessel Network and the Nodes and Organs. Lymphatic vessels and ducts provide the complex transportation network of the lymphatic system.

Detailed explanation-4: -Lymph (or lymphatic ) vessels are thin-walled valved structures that carry lymph. Lymph vessels are lined by endothelial cells and have a thin layer of smooth muscles and adventitia that bind the lymph vessels to the surrounding tissue.

Detailed explanation-5: -Lymph vessels-vessels that carry lymph throughout your body. They are different from blood vessels. Lymph nodes-glands found throughout the lymph vessels. Along with your spleen, these nodes are where white blood cells fight infection.

Detailed explanation-6: -Lymph. Lymph is a fluid similar in composition to blood plasma. Lymphatic Vessels. Lymphatic vessels, unlike blood vessels, only carry fluid away from the tissues. Lymphatic Organs.
