Question

cartilage in the slap in the entrance of trachea​

Answer 1

The cartilage flap called the epiglottis is located in front of the larynx and behind the tongue. ... While swallowing, the epiglottis flattens backward to cover the entrance to the larynx and prevent food from entering the lungs and windpipe. The epiglottis returns to its usual position after swallowing.
