牛蛙的呼吸过程中有两种短期循环事件，口腔振荡和通气循环。在通气过程中，青蛙将空气充满口腔，然后将肺内容物通过口腔吹出，最后关闭鼻孔，同时将口腔内容物泵入肺部。肺排出物通过口腔内容物流动，混合最少，相对纯净的空气被泵入肺部。颊部振荡主要用于在呼吸周期之间冲洗颊腔。
Two short-term cyclic events, buccal oscillations and ventilatory cycles, occur in the bullfrog's respiration. During ventilation the frog fills the buccal cavity with air, then blows the pulmonary contents through the buccal cavity, and finally closes the nostrils while pumping the buccal contents into the lungs. The pulmonary efflux streams by the buccal contents with minimal mixing, and relatively pure air is pumped into the lungs. Buccal oscillations serve mainly to flush out the buccal cavity between ventilatory cycles.
