What happens to a frogs lungs when air is pumped into the glottis?

When air is pumped into a frog's glottis, it enters the lungs, causing them to expand. This process is part of the frog's unique respiratory mechanism, as they can also absorb oxygen through their skin. The expansion of the lungs increases the pressure inside, allowing for gas exchange to occur, which is crucial for oxygenating the frog's blood. Ultimately, this mechanism aids in the frog's ability to breathe both in water and on land.
