Detailed explanation-1: -What is the larynx? Your larynx is part of your respiratory system. It’s a hollow tube that lets air pass from your throat (pharynx) to your trachea on the way to your lungs. It also contains your vocal cords and is essential to human speech, so it’s often called the voice box.

Detailed explanation-2: -The epiglottis, at the upper part of the larynx, is a flaplike projection into the throat. As food is swallowed, the whole larynx structure rises to the epiglottis so that the passageway to the respiratory tract is blocked.

Detailed explanation-3: -The larynx sits at the top of the trachea. The trachea, or the windpipe, is a tube made of cartilage that allows air to travel to and from the lungs. The vocal folds, also called vocal cords, sit inside the larynx.
