Which animals use positive pressure breathing to ventilate their lungs?

Question

Quizplus · Accepted Answer

Frogs use positive pressure breathing, which involves actively pushing air into their lungs by creating a positive pressure in the buccal cavity. This is different from the negative pressure breathing seen in mammals like dogs, where air is drawn into the lungs by expanding the chest cavity. Birds and reptiles do not use positive pressure breathing; birds have a unique air sac system for breathing, and reptiles generally use costal breathing, expanding their rib cage to draw air into the lungs.
