Question

The epiglottis:

A) prevents the acidic contents of the stomach from entering the small intestine.
B) allows partially digested food to move from the esophagus into the stomach.
C) prevents the movement of food or liquid into the trachea.
D) allows the unabsorbed material from the small intestine to move into the large intestine.

Answer 1

The epiglottis is a structure that prevents food or liquid from entering the trachea during swallowing, ensuring it passes only into the esophagus.

Step-by-step explanation:

The epiglottis is a cartilaginous flap that protects the glottis, which is the opening to the trachea. Its main function is to prevent the movement of food or liquid into the trachea during the process of swallowing.

When we swallow, the epiglottis closes off the glottis, allowing food to pass into the esophagus and not the trachea.

This mechanism helps in keeping the respiratory tract clear of food and liquid, which is crucial for preventing aspiration.
