Yes adenoids are part of immune system. It is the first line of defense.
Adenoids
The adenoids are located at the back of your nasal cavity. The adenoids are glands that are part of the immune system and help the body fight infections.
The portion of the pharynx that connects to the nose and contains the adenoids is the nasopharynx. Adenoids are a collection of lymphoid tissue located in the back of the nasopharynx, near the opening of the eustachian tube. They are part of the immune system and help protect the body from infections.
Adenoids are glands located at the back of the nasal passage where they help the body fight off infections by trapping germs that enter the throat. They are part of the immune system in children and usually shrink in size as children grow older.
The largest lymphatic organ in the body is the spleen, not the tonsils and adenoids. The spleen helps filter blood, store blood cells, and fight infection. Tonsils and adenoids are part of the lymphatic system as well, located in the throat, and play a role in immune function by helping to trap germs that enter through the mouth and nose.
The immune system is not considered one of the 11 main organ systems because it consists of a network of cells, tissues, and organs rather than a single distinct system. It works closely with other systems to protect the body from infections and diseases.
adenoids, thyroid, tonsils, spleen
Palatine tonsils and adenoids are NOT synonymous. Palatine tonsils, sometimes called faucial tonsils, are found at the back of the throat. Adenoids are the pharyngeal tonsils, located in the back of the nasal cavity.
The lymphatic tissue in the posterior wall of the pharynx near the auditory tubes is known as the pharyngeal tonsil, or adenoids. This specialized tissue helps to fight infections and can become enlarged and cause issues with breathing and hearing when infected. The adenoids are part of the body's immune system and play a role in protecting against pathogens entering through the nose and throat.
cortisole i guess you mean which is secreted from adrenal its not a part of immune system but it has a permissive act in immunity
Only if there is a medical reason to do so. In most cases, the adenoids are only removed as part of a tonsillectomy.
Normally the adenoids, like the palatine tonsils located on either side of the throat, help prevent infection in the surrounding tissues. However, when they become enlarged they interfere with normal breathing and sometimes with hearing. When severely enlarged, adenoids can affect normal dental development, resulting in an alteration of facial expression. Infection of the adenoids is common, the symptoms resembling those of tonsillitis, with which it is frequently associated. Surgical removal of the adenoids is advisable when enlargement and repeated infection interfere with development and health.Source: Answers.com
