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: -Inside the lymph nodes, lymphocytes called T-cells and 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-3: -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.
