The subsurface capillary networks of the ascending colon were honeycomb-like and multi-layered, with an average number of capillary layers per capillary loop of 3.28±1.10 (mean±SD). Whereas, those of the sigmoid colon were almost single-layered, and the average number of capillary layers was 1.19±0.39. In the cross-section of vascular casts of both parts of the colon, the ascending capillaries originating from the submucosal arterioles ascended into the mucosal layer and joined into the subsurface capillary networks, which drained into the collecting venules near the surface. The mean diameter of the collecting venules of the ascending and the sigmoid colon was 29.03±6.41 μm and 19.48±2.23 μm, respectively. From these findings, it is speculated that the multi-layered capillary networks of the proximal colon are closely related to the greater water absorption and electrolyte transport activities compared to those of the distal colon. © 1996 Oxford University Press Full-length Papers nationallicence blood vessel nationallicence corrosion cast nationallicence human colon nationallicence water absorption nationallicence scanning electron microscopy (SEM) nationallicence Araki Keijiro Department of Surgery, Osaka Medical School, Takatsukl, Osaka, 569 Japan, Nankoku, Kochi, 783 Japan aut Furuya Yasuo Department of Surgery, Osaka Medical School, Takatsukl, Osaka, 569 Japan, Nankoku, Kochi, 783 Japan aut Kobayashi Michiya Department of Surgery, Osaka Medical School, Takatsukl, Osaka, 569 Japan, Nankoku, Kochi, 783 Japan aut Matsuura Kimio Department of Surgery, Osaka Medical School, Takatsukl, Osaka, 569 Japan, Nankoku, Kochi, 783 Japan aut Ogata Takuro Department of Surgery, Osaka Medical School, Takatsukl, Osaka, 569 Japan, Nankoku, Kochi, 783 Japan aut Isozaki Hiroshi Department of Surgery, Osaka Medical School Takatsukl, Osaka, 569 Japan aut Microscopy Oxford University Press 45/3(1996-06), 202-206 0022-0744 45:3<202 1996 45 jmicro https://doi.org/10.1093/oxfordjournals.jmicro.a023433 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1093/oxfordjournals.jmicro.a023433 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Araki Keijiro Department of Surgery, Osaka Medical School, Takatsukl, Osaka, 569 Japan, Nankoku, Kochi, 783 Japan aut NATIONALLICENCE 700 1- Furuya Yasuo Department of Surgery, Osaka Medical School, Takatsukl, Osaka, 569 Japan, Nankoku, Kochi, 783 Japan aut NATIONALLICENCE 700 1- Kobayashi Michiya Department of Surgery, Osaka Medical School, Takatsukl, Osaka, 569 Japan, Nankoku, Kochi, 783 Japan aut NATIONALLICENCE 700 1- Matsuura Kimio Department of Surgery, Osaka Medical School, Takatsukl, Osaka, 569 Japan, Nankoku, Kochi, 783 Japan aut NATIONALLICENCE 700 1- Ogata Takuro Department of Surgery, Osaka Medical School, Takatsukl, Osaka, 569 Japan, Nankoku, Kochi, 783 Japan aut NATIONALLICENCE 700 1- Isozaki Hiroshi Department of Surgery, Osaka Medical School Takatsukl, Osaka, 569 Japan aut NATIONALLICENCE 773 0- Microscopy Oxford University Press 45/3(1996-06), 202-206 0022-0744 45:3<202 1996 45 jmicro Metadata rights reserved CC BY-NC-4.0 http://creativecommons.org/licenses/by-nc/4.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-oxford
