Why do people have tonsils?

[Edit]

Answer

Tonsils are a special type of lymphatic tissue that filters and cleanses lymph; sort of like the air filter on an engine.

Answer

The tonsils and the adenoids are composed of lymphatic tissue and are part of the body's lymphatic system.

They are situated at the top of the throat, where the mouth and nose come together. The adenoids are also found in the back of the throat but located higher on the roof of the mouth behind the nose. Tonsils may be viewed easily through the open mouth, but adenoids require a special instrument to be seen.

The tonsils and adenoids are strategically positioned to monitor potentially-harmful substances that are ingested or inhaled.

Both organs guard against illness by identifying harmful bacteria, fungi, and viruses in food or the air. The white blood cells housed in the tonsils and adenoids incapacitate the invading germs, as well as help produce antibodies to ward against future infections.

For the most part, the tonsils and adenoids have finished serving their purpose by early childhood.

Unfortunately, continual infiltration with bacteria can lead to chronic infections of the tonsils and adenoids. When large amounts of scar tissue develop as a result, doctors usually recommend that they are removed.
