GENERAL HISTOLOGY

Detailed explanation-1: -The epiglottis is usually upright at rest allowing air to pass into the larynx and lungs. When a person swallows the epiglottis folds backward to cover the entrance of the larynx so food and liquid do not enter the windpipe and lungs. After swallowing the epiglottis returns to its original upright position.

Detailed explanation-2: -When you swallow, a flap called the epiglottis moves to block the entrance of food particles into your larynx and lungs. The muscles of the larynx pull upward to assist with this movement. They also tightly close during swallowing.

Detailed explanation-3: -The flap that covers the trachea during swallowing so that food does not enter the lungs. Anatomy of the larynx. The three parts of the larynx are the supraglottis (including the epiglottis), the glottis (including the vocal cords), and the subglottis.

Detailed explanation-4: -The epiglottis is a small, movable “lid” just above the larynx that prevents food and drink from entering the windpipe.

Detailed explanation-5: -The opening of pharynx into the trachea is guarded by the flap like structure called epiglottis which prevents the entry of food in the respiratory tract.
