What are the functions when swallowing tongue, epiglottis and palatine tongue?

The tongue mixes the crushed food and pushes it to the throat. When the muscles of the tongue and pharynx contract, a person swallows.
The epiglottis is an elastic cartilage in the form of a leaf located in the area of ​​the beginning of the tracheal tube, lower from the root of the tongue. The organ has two muscles – scooped and thyroid nodule. When they contract, the swallowing function is triggered, and the epiglottis lowers, closing the passage into the trachea so that the food passes into the esophagus. This is the main task of the body.
The main function of the tongue is to close the nasopharynx when talking or swallowing. It controls the entry and exit of food into the digestive tract. If food touches the tongue, a spasm of the throat occurs, preventing the person from choking. In addition, if there was no tongue, food could enter the nasal cavity. Thus, the tongue during swallowing forms a protective partition.
