GENERAL HISTOLOGY

Detailed explanation-1: -In anatomy, the adenoid, also known as the pharyngeal tonsil or nasopharyngeal tonsil, is the superior-most of the tonsils. It is a mass of lymphatic tissue located behind the nasal cavity, in the roof of the nasopharynx, where the nose blends into the throat.

Detailed explanation-2: -Like tonsils, adenoids help keep the body healthy by trapping harmful bacteria and viruses that we breathe in or swallow. Adenoids (AD-eh-noyds) do important work as infection fighters for babies and young children. But they become less important as a child gets older and the body develops other ways to fight germs.

Detailed explanation-3: -The adenoids are lymph nodes located in the back of the throat behind the nose. Lymph nodes make up part of the lymphatic system, which helps the immune system to fight infection. Other lymph nodes are located in many places, including the neck, armpits, chest, abdomen and groin.
