Glossopharyngeal breathing (GPB, glossopharyngeal insufflation, buccal pumping, or frog breathing) is a means of pistoning air into the lungs to volumes greater than can be achieved by the person's breathing muscles (greater than maximum inspiratory capacity).
Malpighi's frog dissection in 1661, proved to be a suitable size that could be magnified to display the capillary network not seen in the larger animals. [16] In discovering and observing the capillaries in the frog's lungs, Malpighi studied the movement of the blood in a contained system. [15]
Ribs are generally absent, so the lungs are filled by buccal pumping and a frog deprived of its lungs can maintain its body functions without them. [69] The fully aquatic Bornean flat-headed frog (Barbourula kalimantanensis) is the first frog known to lack lungs entirely. [72] Frogs have three-chambered hearts, a feature they share with lizards.
[100] [101] Lungs and swim bladders are homologous (descended from a common ancestral form) as is the case for the pulmonary artery (which delivers de-oxygenated blood from the heart to the lungs) and the arteries that supply swim bladders. [102] Air was introduced into the lungs by a process known as buccal pumping. [103] [104]
