Retronasal Passages: The retronasal passages are the airways that connect the nose and the mouth. Also home to a dime-sized patch of nerve endings called the olfactory epithelium. As we inhale through our nose or mouth, this little patch captures airborne aromas and flavors as they pass by, helping us identify thousands of unique aromas.

鼻后通道： 鼻后通道是连接鼻子和口腔的气道。是一块像硬币大小的神经末梢生长的地方，被称为嗅上皮。当我们通过鼻子或嘴吸气时，这块神经末梢可以扑捉空气中的香气和味道，帮助我们分辨成千上万的独特香味。
