What are the Tonsils?

Tonsils are small organs that are located at the back of the throat. These soft tissues are part of the lymphatic system that makes an important part of the immune system. 

 

You can see the tonsils by opening the mouth wide in front of a mirror. The two fleshy bumps that you see at the sides and back of the mouth are the tonsils. 

 

These were once considered useless organs as they are made obsolete by evolution. Although small glands, these are considered very important.

There are three types of tonsils in the body-

  1. Pharyngeal tonsils

    These tonsils are present near the pharynx which are present since birth and by the time someone reaches preteen, they disappear. When this type of tonsils swells, these are known as adenoids.

  2. Palatine tonsils

    What we commonly refer to as the tonsils are palatine tonsils. These look as if they are coming from each side and are exposed to the mouth cavity.

  3. Lingual tonsils

    Located at the base of the tongue, this type of tonsils have several pits that make the tongue surface look irregular.

What are the functions of tonsils?

Tonsils have several uses. The main function of the tonsils is to trap the germs that are entering the body when you breathe in. They act as the first line of defense when infectious germs enter the body. For instance, the tonsils detect bacteria and viruses that enter the body through the mouth and nose and flush them through the lymph, which is a clear and colorless fluid.

In addition to the defense system, the tonsils also prevent foreign objects from sliding into the lungs. 

These also filter out bacteria and viruses. Moreover, these also produce white blood cells and antibodies. 

What is the size and location of tonsils?

The size of tonsils varies with age. In young babies and adults, the tonsils are very small and are barely visible. In children belonging to the age group of two to five, the tonsils enlarge in size, so much so that they can touch each other. Although generally not a concern, they can cause some problems while sleeping at night.
