buccal pumping
Information about buccal pumping
Buccal pumping is a method of respiration using the throat muscles. Animals using this method will typically move the floor of the mouth or throat in a rhythmic manner that is externally apparent.
This method has several stages. These will be described for an animal starting with lungs in a deflated state: First, the glottis (opening to the lungs) is closed, and the nostrils are opened. The floor of the mouth is then depressed (lowered), drawing air in. The nostrils are then closed, the glottis opened, and the floor of mouth raised, forcing the air into the lungs for gas exchange. To deflate the lungs, the process is reversed.
This method of ventilation is inefficient, but is nonetheless used by all air-breathing amphibians and is utilized to a varying extent by various reptile species. Mammals, in contrast, use the thoracic diaphragm to inflate and deflate the lungs more directly.

In animal physiology, respiration is the transport of oxygen from the ambient air to the tissue cells and the transport of carbon dioxide in the opposite direction. This is in contrast to the biochemical definition of respiration, which refers to cellular respiration

nostril (or naris, pl. nares) is one of the two channels of the nose, from the point where they bifurcate to the external opening. In birds and mammals, they contain branched bones or cartilages called turbinates, whose function is to warm air on inhalation and
