Question

What do internal nares of a frog do?

Answer 1

Internal nares are on the roof of a frog's mouth. Air passes from the external nares into the mouth through these openings. They can be closed using a sphincter muscle when the frog is submerged under water to prevent water from entering the mouth and therefore the lungs.
