Cloaca is in contact with which tissues?

Explanation:
The boundary at the cloacal region is where endodermal tissue lining the gut meets surface ectoderm. The cloaca is an endoderm-lined chamber, and its external surface is covered by surface ectoderm; where they meet forms the cloacal membrane. Mesoderm surrounds this area but does not create the direct inner–outer contact of the cloaca. So the cloaca is in contact with both surface ectoderm and endodermal tissue.
