The glottis closes to shield the opening to the trachea (windpipe), and the food is forced into the large opening at the beginning of the esophagus. For taste and capturing pray. The characteristic croaking is produced because of the vibrations formed when the air from lungs is forced outside.
The air flow causes the vocal chords to vibrate and produce sound. Frogs give birth to young in different ways. Up to this point the mechanism responsible for transmitting sound energy from the frog larynx to the external air has remained elusive.
Vocal sacs are outpocketings of the floor of the mouth, or buccal cavity.

Only male frogs have vocal sacs so as to amplify the croaking sound.
They also use their voices to claim territory, to warn away rivals, and to frighten off predators. Secondly, what is the function of the pancreas in a frog? The vocal apparatus of the male frog is much larger than that of the female.

A single median throat sac, paired throat sacs, and paired lateral sacs. When a frog calls, it forces air from its lungs through its vocal cords, which vibrate, causing the sound. In this paper i explore these different hypotheses and present evidence supporting the function of the vocal sac as a structure amplifying the sound that originates in the vocal cords.
