Name three gaseous exchange in frogs
1) Pulmonary respiration: Frogs have lungs and exchange gases, such as oxygen and carbon dioxide, with the surrounding air. They take in oxygen from the air through their lungs and release carbon dioxide.
2) Cutaneous respiration: Frogs also have a thin, moist skin that allows them to exchange gases directly with the environment. Oxygen in the air dissolves in the moisture on their skin and passes into their bloodstream, while carbon dioxide is released in the same way.
3) Buccal respiration: Frogs can also exchange gases through their buccal cavity, which includes the mouth and nostrils. During buccal respiration, frogs move their throat muscles to force air in and out of the lungs, aiding in exchange of gases. This type of respiration is particularly important when frogs are underwater and cannot rely solely on pulmonary or cutaneous respiration.
