1.Teeth:
Teeth are complex structures made of their own materials. They are made of a bone-like substance called dentin, which is covered with the heaviest tissues in the body - its enamel. [8] Teeth have a variety of mechanisms that deal with various digestive processes that are used to tear and chew food pieces into smaller and smaller pieces. This leads to a much larger area for the production of digestive enzymes. Teeth are named after their specific roles in the digestive process - incisors used to cut or bite food pieces; canines, used for tearing, premolars and molars used for chewing and grinding. The absorption of food with the help of saliva and mucus results in the formation of a soft bolus that can be swallowed so that it goes down the upper intestine to the stomach. [19] The digestive enzymes also help keep teeth clean by breaking down any food particles included. [20] [15]

2.Epiglottis:
The epiglottis is the key to the elastic band attached to the entrance to the larynx. It is covered with a mucous membrane and there are taste buds on the surface of its tongue facing the mouth. [21] Its face is lined with a throat. The epiglottis works to monitor the penetration of the glottis, opening between vocal folds. It is usually pointed upwards as it breathes and its function below as part of the pharynx, but during swallowing, the epiglottis wraps up to a greater extent, its upper side acting as part of the pharynx. In this way it prevents food from entering the trachea and instead directs it down the throat, the back. During swallowing, backward movement of the tongue forces the epiglottis over the glottis hole to prevent any swallowed food from entering the larynx leading to the lungs; the throat is also pulled upwards to aid the process. Throat stimulation with the implant produces a strong cough reflex to protect the lungs.
