1 Acute tonsillitis: A bacteria or virus infects the tonsils, causing swelling and a sore throat. The tonsil may develop a gray or white coating (exudate).  Chronic tonsillitis: Persistent infection of the tonsils, sometimes as a result of repeated episodes of acute tonsillitis.

Each tonsil is composed of tissue similar to lymph nodes, covered by pink mucosa (like on the adjacent mouth lining). Running through the mucosa of each tonsil are pits, called crypts. The tonsils are part of the lymphatic system, which helps to fight infections. However, removal of the tonsils does not seem to increase susceptibility to infection. Tonsils vary widely in size and swell in response to infection.

We're sorry, an error occurred. The palatine tonsils are located at the back of the throat. One tonsil is located on the left side of the throat and the other is located on the right side. The tonsils play a role in protecting the body against respiratory and gastrointestinal infections.

Home > Digestive System > Digestive System of the Head and Neck > Oral Cavity > Palatine Tonsils. The palatine tonsils (what the term tonsils generally refer to) are two lymphatic tissue masses. There is one located on each side of the oral pharynx, in the back of the throat. The function of palatine tonsils has yet to be discovered, however they are part of the immune system and are thought to assist in defending the body from respiratory infections.

For the structure in the cerebellum, see cerebellar tonsil. Tonsils are collections of lymphoid tissue facing into the aerodigestive tract. The set of lymphatic tissue known as Waldeyer's tonsillar ring includes the adenoid tonsil, two tubal tonsils, two palatine tonsils, and the lingual tonsil.

Tonsillitis is a disorder in which the tonsils are inflamed (sore and swollen). The most common way to treat it is with anti-inflammatory drugs such as ibuprofen, or if bacterial in origin, antibiotics, e.g. amoxicillin and azithromycin. Often severe and/or recurrent tonsillitis is treated by tonsillectomy.

If the lymphatic system didn't drain the excess fluid from the tissues, the lymph fluid would build up in the body's tissues, causing them to swell. The lymphatic system also helps defend the body against germs (viruses, bacteria, and fungi) that can cause illnesses. Those germs are filtered out in the lymph nodes, which are small masses of tissue located along the network of lymph vessels. The nodes house lymphocytes, a type of white blood cell.

The palatine tonsils and the nasopharyngeal tonsil are lymphoepithelial tissues located near the oropharynx and nasopharynx (parts of the throat).

The lymphatic system is a network of very small tubes (or vessels) that drain lymph fluid from all over the body. The major parts of the lymph tissue are located in the bone marrow, spleen, thymus gland, lymph nodes, and the tonsils. The heart, lungs, intestines, liver, and skin also contain lymphatic tissue.

However, your feedback is important to us. The palatine tonsils are located at the back of the throat. One tonsil is located on the left side of the throat and the other is located on the right side. The tonsils play a role in protecting the body against respiratory and gastrointestinal infections. Each tonsil consists of a network of crypts (pits) that store cells used to fight infection.
