The tube that runs from the middle ear to the nasopharynx, also known as the Eustachian tube. The function of this tube is to protect, aerate and drain the middle ear (and mastoid). Occlusion of the Eustachian tube leads to the development of middle ear inflammation (otitis media). This tube, in medical Latin, is called the tuba acustica, tuba audi [..]

The tube that runs from the middle ear to the pharynx. The function of the Eustachian tube is to protect, aerate and drain the middle ear (and mastoid).

The two Fallopian tubes, one on each side, transport the egg from the ovary to the uterus (the womb). The Fallopian tubes have small hair-like projections called cilia on the cells of the lining. These tubal cilia are essential to the movement of the egg through the tube into the uterus. If the tubal cilia are damaged by infection, the egg may not [..]

See: Nasogastric tube.

An NG (nasogastric) tube is one that is passed through the nose (via the nasopharynx and esophagus) down into the stomach. An NG tube is a flexible tube made of rubber or plastic and has bidirectional potential. A nasogastric tube can thus be used to remove the contents of the stomach including air (to decompress the stomach) and small solid object [..]

The tube that runs from the middle ear to the pharynx, known also as the Eustachian tube. The function of this tube is to protect, aerate and drain the middle ear (and mastoid). Occlusion of the Eustachian tube leads to the development of middle ear inflammation (otitis media) or middle fluid. This tube is also called the auditory tube (and in medi [..]

See: Swallowing tube.

A small tube inserted into the eardrum to keep the middle ear aerated for a prolonged period of time. These ventilating tubes usually remain in place for 6 months to several years. Eventually, they move out of the eardrum (extrude) and fall out into the ear canal. Also called ear tubes.
