What is the elastic cartilage that shields the opening to the widpeip during swallowing?

The elastic cartilage that shields the opening to the windpipe during swallowing is known as the epiglottis. It acts as a flap that covers the larynx, preventing food and liquid from entering the trachea and directing them toward the esophagus. This mechanism helps protect the airway, ensuring that only air passes into the lungs while swallowing. The epiglottis is flexible due to its elastic cartilage composition, allowing it to move easily during the swallowing process.
