IMMUNOLOGY

Detailed explanation-1: -Summary. The lymphatic system is our body’s ‘sewerage system’. It maintains fluid levels in our body tissues by removing all fluids that leak out of our blood vessels. The lymphatic system is important for the optimal functioning of our general and specific immune responses.

Detailed explanation-2: -Protects your body against foreign invaders: The lymphatic system is part of the immune system. It produces and releases lymphocytes (white blood cells) and other immune cells that monitor and then destroy the foreign invaders-such as bacteria, viruses, parasites and fungi-that may enter your body.

Detailed explanation-3: -The lymphatic system (lymph, lymph nodes and lymph vessels) supports the circulatory system by draining excess fluids and proteins from tissues back into the bloodstream, thereby preventing tissue swelling.

Detailed explanation-4: -There are two routes by which immune cells can enter LNs: leukocytes can arrive from the bloodstream by crossing high endothelial venules (HEVs) (5). Alternatively, tissue-resident immune cells can enter afferent lymphatic vessels and migrate to draining LNs (dLNs) (5–8).

Detailed explanation-5: -The lymphatic system is part of the immune system. It keeps body fluid levels in balance and defends the body against infections. Lymphatic (lim-FAT-ik) vessels, tissues, organs, and glands work together to drain a watery fluid called lymph from throughout the body.

Detailed explanation-6: -What Does the Lymphatic System Do? One of the lymphatic system’s major jobs is to collect extra lymph fluid from body tissues and return it to the blood. This is important because water, proteins, and other substances are always leaking out of tiny blood capillaries into the surrounding body tissues.

Detailed explanation-7: -Lymphatic vessels branch, like blood vessels, into all the tissues of the body. Also called lymph system.
