A description is given of the distribution of the longitudinal mucosal corrugations in the human tracheo-bronchial tree. It has been shown that they are made up of elastic tissue in a collagen matrix, and that the elastic fibres continue into the smallest bronchioles beyond where the corrugations are no longer visible. An examination has also been made of the tracheo-bronchial trees of the hen, rat, raccoon, pig, sheep, llama and tiger. Corrugations are present in all these animals, except the hen and the raccoon, and they have been compared and contrasted with the condition in Man. The functional significance of these corrugations remains unknown, but, they could be important in equalizing tension in the tracheo-bronchial tree during inspiration, as well as in providing elastic recoil during expiration.
本文描述了人类气管支气管树中纵向黏膜皱襞的分布情况。研究表明，它们由胶原基质中的弹性组织构成，且弹性纤维会延伸至最小的细支气管，超出皱襞不再可见的部位。同时还对母鸡、大鼠、浣熊、猪、绵羊、美洲驼和老虎的气管支气管树进行了检查。除母鸡和浣熊外，所有这些动物都存在皱襞，并将它们与人类的情况进行了比较和对比。这些皱襞的功能意义尚不清楚，但它们可能在吸气时平衡气管支气管树中的张力以及在呼气时提供弹性回缩方面具有重要作用。
