Answer:

The external nares are tightly closed and the floor of the distended buccal cavity is forcibly raised. The mixed air is thus pumped into the lungs through the glottis. ... In a living toad, the floor of the buccal cavity is constantly moved up and down, and the mouth is kept closed. This means that the animal is breathing.
