THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The primary function of the epiglottic cartilage is to prevent chewed food and saliva from entering the trachea, resulting in choking. For this reason, the epiglottis folds backwards during swallowing movements as to cover the opening of the larynx so that food and liquid are directed to the esophagus.

Detailed explanation-2: -The epiglottis is a stiff, yet flexible tissue (called cartilage) at the back of the tongue. It closes your windpipe (trachea) when you swallow so food does not enter your airway. This helps prevent coughing or choking after swallowing.

Detailed explanation-3: -If the epiglottis is absent in the body then the regulation of food material to esophagus and air into the lungs will get disturbed. Sometimes food will enter into the windpipe and then causes choking. Eventually, the lungs cannot not work properly which can lead to death.
