What are tonsils?

Tonsils are two small masses of tissue located at the back of the throat, one on each side. They are part of the body's immune system and help to fight off infections by trapping bacteria and viruses that enter the body through the mouth and nose. Tonsils can become inflamed and swollen, a condition known as tonsillitis, which can cause symptoms such as sore throat, difficulty swallowing, and fever. In some cases, tonsils may need to be surgically removed if they become chronically infected or enlarged.

Tonsils are small, round masses of lymphoid tissue located at the back of the throat. They are part of the body's immune system and help to protect against infection. Tonsils are made up of a network of lymph nodes and blood vessels. They are covered by a layer of mucous membrane.

There are two main types of tonsils:

- Palatine tonsils are located on either side of the back of the throat. They are the most common type of tonsil.
- Lingual tonsils are located at the base of the tongue. They are not as common as palatine tonsils.

Tonsils are active in the immune system. They trap bacteria and viruses that enter the body through the mouth or nose. The tonsils then produce antibodies to fight off the infection.

Tonsils can become infected or enlarged. This can cause a sore throat, difficulty swallowing, and pain in the ears. In some cases, it may be necessary to remove the tonsils.
