the caudal part of the alimentary canal in vertebrate embryos

The section of an iguana's intestine that lies between the small and large intestines. The hindgut houses populations of helpful gut bacteria which break down the hard-to-digest cellulose that is a component of all plant foods.

Hindgut (or epigaster) is the posterior (caudal) part of the alimentary canal. It includes the distal third of the transverse colon and the splenic flexure, the descending colon, sigmoid colon, and rectum. The hindgut ends at the recto-anal junction.
