What is fauces in mouth?

The fauces is the opening at the back of the mouth where the oral cavity transitions into the pharynx, which leads to the esophagus and trachea. It is surrounded by two arches called the palatoglossal arch and palatopharyngeal arch. The uvula is located in the center of the fauces. The fauces plays an important role in swallowing and breathing, as it allows air and food to pass from the mouth to the throat and digestive system. It is also an important area for dental hygiene, as bacteria can accumulate in this area and lead to bad breath and infections.
