The tonsils are lymph node organs located at the level of the mouth and pharynx. With the term linfoghiandola means a body having anti-infective and immune function, the task of the tonsils, in particular, is to protect the organism from pathogens that can invade the tissues around the orifices waterpik ultra water flosser of the nasal cavity and oral. Other common lymph glands, which are present in the human body are the lymph nodes.
The tonsils are distributed in different areas, including the oral cavity and pharynx, therefore, are identified by different names according to their location, they are in particular: the palatine tonsils, two in number (in common parlance, when we talk generically tonsils are the palatine tonsils), the tonsil (rhino) pharyngeal (in common parlance, is often called adenoid, and when it is inflamed, and swollen, it is called adenoids), the lingual tonsil. Anatomy of the tonsils
The tonsils are conspicuous clusters of lymphoid tissue, so that can be considered true organs. A pharyngeal level, for greater completeness, in areas such thickening alternating with less dense areas of lymphoid tissue (here, we talk about the specifics of adenoid tissue).
The lymphoid tissue (also known as lymphatic tissue or lymphoreticular) consists largely of cells called lymphocytes, supported by a network connective tissue. Specifically, both tonsillar recognizes a connective tissue scaffold with capillaries, arterioles and venules. In it, they place the lymphoid follicles (or lymphatic), which are aggregates of lymphocytes, waterpik ultra water flosser ie cells with anti-infective and immune function.
The palatine tonsil mass ovoid shape. Size and shape reminiscent of an almond, and this explains why it is also known as the amygdala, word of Greek origin, which indicates this almond. In the human body there are two palatine tonsils, staying in a symmetrical manner in a region called the isthmus mouth. This area connects the mouth and pharynx, is formed by curved structures and on the sides of them, are precisely the palatine tonsils.
Given their location, the palatine tonsils are the only ones visible. The precise dimensions of a single palatine tonsil may vary from individual to individual, the average data reported such measures: waterpik ultra water flosser height: 20-25 mm. Length: 15 mm approx. thickness: 10 mm.
The surface of the palatine tonsil is covered by the pharyngeal mucosa. The mucosa is the portion of tissue in direct contact with the lumen of hollow organs animals. The epithelium lining the pharyngeal mucosa is classified as pavimentoso stratified, that is formed by flattened cells overlap. Through histological analysis tonsillar epithelium can be seen cavities, called crypts, also very deep. These structures allow to expand the area of contact with that which penetrates from the outside in the oral cavity, allowing a more efficient against germs and bacteria. Inside of the crypts is collected, in fact, the secreted mucous containing the cells of the immune system.
The pharyngeal waterpik ultra water flosser tonsil is located at the level of the nasopharynx, ie the upper part of the pharynx, the time between pharyngeal and the upper face of the palate. It is also called the amygdala (pharyngeal in this case) by virtue of its shape, similar to that of an almond; most commonly is known as adenoid. Similarly the palatine tonsil, its histological structure envisages the presence of crypts. It is a particular waterpik ultra water flosser organ: waterpik ultra water flosser after birth develops progressively to 7-8 th year, at which time begins to atrophy in a natural way almost to disappear, in some cases, into adulthood.
The lingual tonsil is located behind and to the base of the tongue. This area is covered by agglomerates follicular, ie from lymphoid tissue, including creep of circular grooves. These grooves are contained the tonsillar crypts, about 2-3 mm deep. As the pharyngeal tonsil, even the tongue undergoes a process of regression from the age of about 14 years. Around 20 years, the reduction of the lingual tonsil is complete, so that there are only a few small follicles. Functions of the tonsils
Because of their location, situated waterpik ultra water flosser at the beginning waterpik ultra water flosser of the respiratory and digestive tracts of those, and their composition lymphoid, tonsils play a specific waterpik ultra water flosser role: they are the first barriers of defense against germs and bacteria that penetrate from the outside, waterpik ultra water flosser through the 'air and foodstuffs. The anti-infective and immune action is favored by the presence of the crypts. There are two reasons: The invaginations, or cavities, increase the contact surface between the tonsillar epithelium and external pathogens. In this way, the anti-infective action is more efficient. The epithelium of the crypts produces, within the
