I’ll take this as a general respiratory system question. Unlike humans, oxygen can pass through a frogs skin and go directly into the blood stream, but they still have and breathe with lungs. Like humans, frogs breathe through their mouths and nostrils, but their chest and ribs do not control their breathing–that is why the throat puffs out. Humans have little hairs in the nose, which only mammals have, so frogs do not have nose hair.
