B) prevent the entrance of food and water into the respiratory passages.
C) are structures of the larynx.
D) are composed of tough cartilage.

Accepted Answer

The epiglottis, glottis, and vocal cords are all structures of the larynx, which is commonly referred to as the voice box. The larynx is responsible for producing sound through the vibration of the vocal cords during exhalation. While the epiglottis does play a role in preventing the entrance of food and water into the respiratory passages, it is not the primary function of these structures. Additionally, while the larynx is composed of cartilage, it is not described as tough.
