Explanation: 

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.

This ring protects the entrance of the GIT and the respiratory tract. It is formed superiorly by the pharyngeal tonsils, also known as adenoids, in the roof of the nasal pharynx.
