Where do the Eustachian tubes lead in a frog?

What is the mechanics of an insect's pharynx?
An insect's pharynx works by contracting muscles to help push food downwards toward the esophagus. The pharynx also helps regulate the flow of air during respiration by controlling the opening and closing of the respiratory system. Insects have a tube-like structure that extends from the pharynx to the gut, allowing for both food and air to pass through.
