Which is the Correct Order of Action for the Amphibian

Question

Which is the correct order of action for the amphibian "balanced breath"?
A)buccal cavity expands,glottis opens,spent air leaves lungs,buccal cavity contracts
B)buccal cavity expands,spent air leaves lungs,glottis opens,buccal cavity contracts
C)glottis opens,buccal cavity expands,buccal cavity contracts,spent air leaves lungs
D)spent air leaves lungs,glottis opens,buccal cavity expands,buccal cavity contracts

Accepted Answer

The correct sequence for the amphibian "balanced breath" starts with the expansion of the buccal cavity, which draws air in through the nostrils. Then, the glottis opens, allowing the spent air to leave the lungs. Finally, the buccal cavity contracts, pushing fresh air into the lungs. This process ensures efficient gas exchange in amphibians.
