Tonsils help defend the body against infections by trapping and filtering out bacteria and viruses that enter through the mouth and nose. They play a role in the immune response by producing antibodies to fight off these pathogens.
1- skin 2- WBCs present in the blood 3- even fever and inflammations can be considered as defences 4- production of immunoglobulins 5- HCL acid produced by the stomach and there are too many others defences that can be studied in each organ or biological system specifically
