- A. Epiglottis
- B. Diaphragm

Explanation
The epiglottis is a small flap of tissue located at the base of the tongue, near the entrance of the windpipe (trachea). Its primary function is to prevent food and liquids from entering the airway during swallowing. It covers the opening of the trachea, directing the food down the esophagus and into the stomach. If the epiglottis doesn't function properly or fails to close properly, it can lead to food or liquid entering the airway, causing coughing or choking.
