COLON

Slide #136 (cat) - methacrylate.  The lumen surface is particularly flat here.  Also, the contents of the goblet cells are well preserved and rather globular looking.  Follow along the outermost coat of the colon and notice a shift from serosa to a wide mesenteric attachment.  Follow the surface mesothelium (simple squamous epithelium) as it covers the mesentery.
