Tonsils help defend against which of the following pathogens?

The key idea here is how the tonsils contribute to immunity at the entry points of the body. Tonsils are part of the mucosal immune system and act as a first line of defense in the throat. They trap microbes that enter through the mouth and nose and contain immune cells that respond by producing antibodies and initiating a local immune response. Because their job is to neutralize living infectious agents, they defend against micro-organisms such as bacteria and viruses. Allergens are substances that trigger allergic reactions rather than infections, so they’re not the pathogens tonsils are designed to combat. Parasites are a different kind of threat and aren’t the primary targets of tonsillar immune activity. Fungi are a type of micro-organism, but the general description of what tonsils defend against is micro-organisms, which covers the typical bacteria and viruses encountered in the upper airways.
