About the Tonsils

The tonsils are part of the body's defense system. Because of their location at the throat and palate, they have a kind of guardian function. They come into contact with germs especially soon after they enter through the mouth or the nose. This allows them to activate the immune system early.

The tonsils include the following types:

Terms to know

A protein produced by the immune system in response to a foreign substance such as a virus or bacterium.
The organ that stores urine.
Buccal Mucosa (Mouth Mucosa)
The inner lining of the cheeks.
Colon (Bowel)
The longest part of the large intestine, which is a tube-like organ connected to the small intestine at one end and the anus at the other. The colon removes water and some nutrients and electrolytes from partially digested food. The remaining material, solid waste called stool, moves through the colon to the rectum and leaves the body through the anus.
Eustachian Tube
A small passageway on either side of the head that connects the upper part of the throat to the middle ear. It supplies fresh air, drains fluid, and keeps air pressure between the nose and the ear at a steady level.
Gingiva (Gums)
The tissue of the upper and lower jaws that surrounds the base of the teeth. Also called gums.
Hard Palate
The front, bony part of the roof of the mouth.
Immune System
The body's system for protecting itself from viruses and bacteria or any foreign substances.
Larynx (Voice Box)
The area of the throat containing the vocal cords and used for breathing, swallowing, and talking. Also called voice box.
Fleshy fold which surrounds the opening of the mouth.
Lymph Nodes
A rounded mass of lymphatic tissue that is surrounded by a capsule of connective tissue. Lymph nodes filter lymph (lymphatic fluid), and they store lymphocytes (white blood cells). They are located along lymphatic vessels. Also called lymph gland.
Lymphatic Tissue (Lymphoid Tissue)
Tissue associated with the lymphatic system, defending the body against infections.
Mucosa (Mucous Membranes)
The moist, inner lining of some organs and body cavities (such as the nose, mouth, lungs, and stomach). Glands in the mucosa make mucus (a thick, slippery fluid). Also called mucous membrane.
A part of the upper respiratory tract. It contains the organ of smell. The term includes the external nose, the nasal cavity, and the paranasal sinuses.
Oral Cavity (Mouth)
Refers to the mouth. It includes the lips, the lining inside the cheeks and lips, the front two thirds of the tongue, the upper and lower gums, the floor of the mouth under the tongue, the bony roof of the mouth, and the small area behind the wisdom teeth.
The part of the throat at the back of the mouth behind the oral cavity.
Palatine Tonsils
The two tonsils that can be seen on the left and right sides at the back of the throat.
Pharyngeal Tonsils (Adenoids)
Small pad of infection-fighting tissue located near the eustachian tube.
Pharynx (Throat)
The hollow tube inside the neck that starts behind the nose and ends at the top of the trachea (windpipe) and esophagus (the tube that goes to the stomach).
Retromolar Trigone
The small area behind the wisdom teeth.
The outer covering of the body that protects it from the environment.
Soft Palate
The back, muscular (not bony) part of the roof of the mouth.
An organ that is part of the lymphatic system. The spleen makes lymphocytes, filters the blood, stores blood cells, and destroys old blood cells. It is located on the left side of the abdomen near the stomach.
Thymus Gland
An organ that is part of the lymphatic system, in which T lymphocytes grow and multiply. The thymus is in the chest behind the breastbone.
A group of cells that act together to carry out a specific function in the body. Examples include muscle tissue, nervous system tissue (including the brain, spinal cord, and nerves), and connective tissue (including ligaments, tendons, bones, and fat). Organs are made up of tissues.
Large muscle on the floor of the mouth that manipulates food for chewing and swallowing. It is the main organ of taste, and assists in forming speech sounds.
Two small masses of lymphoid tissue on either side of the throat.
One of a set of bone-like structures in the mouth used for biting and chewing.
The soft flap of tissue that hangs down at the back of the mouth (at the edge of the soft palate). Also called palatine uvula.
