Amphibians, such as frogs, breathe by collecting air in a pouch below their throat. Muscles then contract the pouch and force air into their lungs. How does this differ from inhalation in humans and other mammals?

Answer:
it differes as frogs donot have a rib cage
Explanation:
A frog may also breathe much like a human, by taking air in through their nostrils and down into their lungs. The mechanism of taking air into the lungs is however sligthly different than in humans. Frogs do not have ribs nor a diaphragm, which in humans helps serve in expand the chest and thereby decreasing the pressure in the lungs allowing outside air to flow in.
The thin membranous skin allows the respiratory gases to readily diffuse directly down their gradients between the blood vessels and the surroundings. When the frog is out of the water, mucus glands in the skin keep the frog moist, which helps absorb dissolved oxygen from the air.
