Buccopharyngeal breathing

WebThe mechanism of lung inflation in amphibians is the buccal cavity (mouth-throat) pumping mechanism that also functions in air-breathing fishes. To produce inspiration, the floor of the mouth is depressed, causing air to be drawn into the buccal cavity through the nostrils. The nostrils are then closed, and the floor of the mouth is elevated. WebThe buccopharyngeal membrane (Latin, bucca = cheek) or oral membrane, forms the external upper membrane limit (cranial end) of the early gastrointestinal tract (GIT).This membrane region first develops in the trilaminar embryo (week 3) during gastrulation and lies above the cranial end of the notochord.The "membrane" quality comes from being …
