ANATOMY

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.

Detailed explanation-2: -The flap that covers the trachea during swallowing so that food does not enter the lungs.

Detailed explanation-3: -The larynx (voice box) is the area that connects the throat to the windpipe (trachea). Without it, we would hardly be able to sing or speak. It also keeps food and drink out of the windpipe.

Detailed explanation-4: -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-5: -larynx is opened or closed by two mechanisms: (1) Contractions of the cricothyroid and of the intrinsic muscles of the larynx open and close the vocal cords. cartilages stretches and opens or shortens and com-presses the soft tissue folds of the intrinsic larynx.
