Detailed explanation-1: -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-2: -Lymph nodes contain lots of white blood cells called lymphocytes. If you have an infection, the lymphocytes multiply inside your lymph nodes. They help fight the infection and make chemicals that activate other parts of your immune system. This is why your lymph nodes swell up when you have an infection.

Detailed explanation-3: -What Is the Lymphatic System? 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-4: -Types of white blood cells Lymphocytes are mature, infection-fighting cells that develop from lymphoblasts, a type of blood stem cell in the bone marrow. Lymphocytes are the main cells that make up lymphoid tissue, a major part of the immune system.
