Detailed explanation-1: -There, white blood cells called lymphocytes can attack and kill the bacteria. Viruses and cancer cells are also trapped and destroyed in the lymph nodes. More lymphocytes are produced when you have an infection.
Detailed explanation-2: -Neutrophils. They kill and digest bacteria and fungi. They are the most numerous type of white blood cell and your first line of defense when infection strikes.
Detailed explanation-3: -Lymph nodes filter substances that travel through the lymphatic fluid, and they contain lymphocytes (white blood cells) that help the body fight infection and disease. There are hundreds of lymph nodes found throughout the body. They are connected to one another by lymph vessels.
Detailed explanation-4: -Lymph nodes drain lymphatic fluid from tissues that are exposed to the external environment, such as the skin, lung, or gut. Pathogens that travel through lymphatics should be able to enter the circulation, if it were not for the strategic localization of lymph nodes along lymphatics which prevent systemic access.
