The Rectum Near the Anorectal Junction

The T2 weighted MRI of the colon in cross section (left image) shows a water filled central cavity (white) bordered by an undulating wall of the bowel.

A photograph of a rotting trees  trunk had a central cavity (black) with a similarly shaped undulating wall.

Artistically the shapes in human biology and botany have marvelous similarities.
