Two friends are eating together at a dining table. One of them suddenly starts coughing while swallowing some food. This coughing would have been due to improper movement of:
The pharynx serves as a common passage for food, fluids, and air. The epiglottis is a flexible flap at the superior end of the larynx in the throat. It acts as a switch between the larynx and the oesophagus. It permits air to enter the trachea and then into the lungs and food to pass into the gastrointestinal tract. If we talk while eating, the food may enter the trachea due to improper movement of the epiglottis. This leads to coughing.
So, the correct answer is 'A' 'Epiglottis'
