Quizplus · Accepted Answer

Tonsils are a part of the body's immune system and help to protect the body from infections by trapping bacteria and viruses that enter the body through the mouth and nose. They produce white blood cells that fight infection and also help to activate the immune system. However, tonsils are not directly involved in the respiratory process of breathing or air exchange.
