Detailed explanation-1: -What are tonsils? Your tonsils are two round, fleshy masses in the back of your throat (pharynx). Part of your immune system, your tonsils are like lymph nodes. They help filter out germs that enter through your nose or mouth to protect the rest of your body from infection.

Detailed explanation-2: -The tonsils are lymphoid tissues that are found at the back of the throat and help fight infection. The tonsils that we all know about are the ones on the sides of the throat and can be seen when you look at your throat in the mirror and these are called palatine tonsils.

Detailed explanation-3: -The lingual tonsil is an aggregate of 30 to 100 follicles along the pharyngeal surface of the tongue, extending from the circumvallate papillae to the root of the epiglottis. This lymphoid tissue causes the normal surface of the base of the tongue to be divided into small nodules of varying size.

Detailed explanation-4: -adenoids, also called pharyngeal tonsils, a mass of lymphatic tissue, similar to the (palatine) tonsils, that is attached to the back wall of the nasal pharynx (i.e., the upper part of the throat opening into the nasal cavity proper). An individual fold of such nasopharyngeal lymphatic tissue is called an adenoid.
