The answer is the second one: Covers the glottis when swallowing.

Explanation for each option:

  1. Covers the posterior nasal aperture when breathing: Incorrect. The epiglottis does not cover the nasal aperture; it is involved in the swallowing process.

  2. Covers the glottis when swallowing: Correct. The epiglottis acts as a flap that covers the glottis (the opening of the windpipe) during swallowing to prevent food and liquid from entering the airway.

  3. Covers the esophagus when breathing: Incorrect. The epiglottis does not cover the esophagus; it is primarily involved in protecting the airway during swallowing.

  4. Covers the glottis when breathing: Incorrect. The epiglottis does not cover the glottis during breathing; it remains open to allow air passage.

Summary: The epiglottis covers the glottis when swallowing to prevent aspiration.
