Vedclass · Answer

(A) Frogs lack a diaphragm,which is the primary muscle responsible for creating negative pressure in the thoracic cavity of mammals to facilitate breathing.Because they do not have a diaphragm or a rib cage that can expand to create a vacuum,they use a mechanism called 'buccopharyngeal respiration' or positive pressure breathing.In this process,the frog swallows air by closing its nostrils and raising the floor of its mouth,which forces air into the lungs.
