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: -Inside the lymph nodes, T-cells and another type of lymphocyte, B-cells, help the body fight infection. B cells make antibodies-special proteins that stop infections from spreading by trapping disease-causing germs and destroying them.

Detailed explanation-4: -The lymph nodes and other lymphatic structures like the spleen and thymus hold special white blood cells called lymphocytes. These can rapidly multiply and release antibodies in response to bacteria, viruses, and a range of other stimuli from dead or dying cells and abnormally behaving cells such as cancer cells.

Detailed explanation-5: -The lymphatic system helps defend the body against illness-causing germs, bacteria, viruses and fungi. The system builds immunity by making special white blood cells (called lymphocytes) that produce antibodies which are responsible for immune responses that defend the body against disease.
