Description
Summary:	The histologic study on six horses of the ileo-caecal and caeco-colic junctions confirms their sphincteral structure. It appears that the activity of the muscular fibres, identified in the ileo-caecal and caeco-colic plica, modulates the curvature of the junctions and thus, blocks, as sphincters, the reflux of contents from the caecum into the ileum and from the colon into the caecum. But on the other hand, the pelvic flexure does not possess any microscopic organization to stop the reflux of contents from the dorsal colon into the ventral colon.
