- Much like other tonsils, the aim of Pharyngeal tonsils is to increase the capability of the lymphatic system against foreign organisms which enter the body through the nose and mouth and pass into the throat. In infants, inflammation of these tonsils acts as a natural defense against infections.

HISTOLOGICAL FEATURES OF TONSIL Waldeyer's Ring of Lymphoid Tissue. The lymphoid tissue that surrounds the opening into the respiratory and digestive systems forms a ring. The lateral part of the ring is formed by the palatine tonsils and tubal tonsils (lymphoid tissue around the opening of the auditory tube in the lateral wall of the nasopharynx).he tonsils constitute a lymphoid tissue that lies beneath, and in contact with, the epithelium of the initial portion of the digestive tract. Depending on their location, tonsils in the mouth and pharynx are called palatine, pharyngeal, or lingual.

- The function of the pharynx is to transfer food from the mouth to the esophagus and to warm, moisten and filter air before it moves into the trachea. The pharynx is a part of both the digestive and respiratory systems. Continue Reading.

Palatine tonsil It refers to one of the tonsils that are visually apparent on the right and left sides at the back of the throat. It is sometimes also referred to as “Faucial tonsil.”In Latin, it is known as “Tonsilla palatina”.alatine tonsil Functions. This structure is mainly responsible for providing protection to the body from infection of the respiratory tract and the digestive system. It also assists the body in trapping bacteria, thus allowing the body the time to manufacture antibodies and destroy invading germs.

- Location of the Tonsils. 1  The pharyngeal tonsil is located in the mucous membrane lining the roof and posterior wall (back wall) of the nasopharynx. It is commonly referred to as the ‘adenoids‘ when inflamed.  The tubal tonsil is located in the submucosa of the nasopharynx near the opening of the eustachian tube.

Picture of the Tonsils Tonsil stones, tonsils The tonsils (palatine tonsils) are a pair of soft tissue masses located at the rear of the throat ( pharynx). Each tonsil is composed of tissue similar to lymph nodes, covered by pink mucosa (like on the adjacent mouth lining). Running through the mucosa of each tonsil are pits, called crypts. The tonsils are part of the lymphatic system, which helps to fight infections. However, removal of the tonsils does not seem to increase susceptibility to infection.

Tonsil and Adenoid Anatomy View of tonsils and adenoids through mouth. Crowe-Davis mouth gag has been used to open oral cavity. Endotracheal tube can be visualized going from mouth through vocal folds into trachea. Palatine tonsils located on either lateral aspect of oropharynx can be easily visualized.

- (1) The tonsils are situated one on each side of the oropharynx, lodged in a tonsillar fossa that is attached to folds of membrane containing muscle. One pair, the palatine tonsils, is the only lymphatic organ covered with stratified squamous epithelium. The lateral surface of each tonsil is usually covered with a fibrous capsule.

Palatine Tonsils There is one located on each side of the oral pharynx, in the back of the throat. The function of palatine tonsils has yet to be discovered, however they are part of the immune system and are thought to assist in defending the body from respiratory infections. The palatine tonsils (what the term tonsils generally refer to) are two lymphatic tissue masses. There is one located on each side of the oral pharynx, in the back of the throat.

Tonsil The third pair of tonsils are the lingual tonsils, aggregations of lymphatic tissue on the surface tissue at the base of the tongue. The surface of this tonsil has pits leading to lower lymphatic tissue as in the other two tonsil types, but these pits are effectively drained by small glands (mucous glands), and infection is rare.

Tonsils Tonsils are clusters of lymphatic tissue just under the mucous membranes that line the nose, mouth, and throat (pharynx). There are three groups of tonsils. The pharyngeal tonsils are located near the opening of the nasal cavity into the pharynx. When these tonsils become enlarged they may interfere with breathing and are called adenoids.

Functions of the Tonsils The tonsils are part of the lymphatic system. Comprised of lymphatic tissue, each tonsil is located on either side of the back of the throat.Usually, tonsils are equal in size, pink in color, and covered with small deep depressions called crypts.Each set of tonsils is composed of three types.he portion of the tonsils referred to as the pharyngeal tonsils or adenoids protect the lungs from bacteria and viruses that enter the body through the nose. They trap harmful inhaled bacteria and produce lymphocytes to destroy the microorganisms before they can reach the lungs.

What is the function of the Uvula? The uvula is a nifty bit of tissue that hangs in the back of your mouth. It plays a function in creating guttural sounds in languages like German, and the click sounds of some … African languages.It does not cover the windpipe during eating and drinking.he function of the Uvula is to not only start the gagging reflex in the event of an emergency (i.e chocking or other airway obstruction) but to also help fight infection. Of … course your tonsils also help but most people have tonsillectomies (surgical removal of the tonsils).

Tonsil Tonsils are collections of lymphoid tissue facing into the aerodigestive tract. The set of lymphatic tissue known as Waldeyer's tonsillar ring includes the adenoid tonsil, two tubal tonsils, two palatine tonsils, and the lingual tonsil. When used unqualified, the term most commonly refers specifically to the palatine tonsils, which are masses of lymphatic material situated at either side of the back of the human throat. The palatine tonsils and the nasopharyngeal tonsil are lymphoepithelial tiss
