通过对美洲大蠊消化系统的苏木精-伊红（H&E）染色、蟑螂幼虫多个断面的研究和三维重建技术，首次建立了美洲大蠊消化系统的三维模型。美洲大蠊的消化系统包括前肠、中肠和后肠，并占据大部分体腔。前肠几乎占消化系统的一半（43.57%）。中肠是消化吸收的关键区域，其体积比第二高（35.21%）。后肠包括回肠、结肠和直肠，容积率最低（21.22%）。回肠瓣之后是结肠。本文提出的三维模型为研究美洲大蠊消化道各段的毗邻关系和排列提供了立体视图。
A three-dimensional (3-D) model of the digestive system of Periplaneta americana was built for the first time based on hematoxylin and eosin (H&E) staining, the study of multiple cross-sections of the larval cockroach, and 3-D reconstruction technology. The digestive system of P. americana includes the foregut, midgut, and hindgut and takes up most of the celom. The foregut comprises almost one half of the digestive system (43.57%). The midgut, the critical region for digestion and absorption, has the second highest volume ratio (35.21%). The hindgut, with the lowest volume ratio (21.22%), includes the ileum, colon, and rectum. After the ileal valve is the colon. The 3-D model presented in this paper provides a stereoscopic view for studying the adjacent relationship and arrangement of different gut sections of P. americana.
