Answer Details
Gaseous exchange takes place in the adult toad through the skin, buccal cavity, and lungs. The skin of the toad is thin and moist, allowing oxygen to diffuse in and carbon dioxide to diffuse out. The buccal cavity, which includes the mouth and nostrils, also plays a role in respiration by allowing air to enter and exit the body. Air is then drawn into the lungs, where oxygen is exchanged with carbon dioxide in the alveoli. This process of gaseous exchange is essential for the toad to obtain the oxygen it needs for respiration and to release the waste product of carbon dioxide.
