Atrioventricular canal

Dorsal surface of heart of human embryo of thirty-five days. (Atrial canal visible at center.)
Latin	canalis atrioventricularis, canalis atrialis
Gray's	subject #135 508
Code	TE E5.11.1.3.2.0.11

In the developing heart, the constriction between the atrium and ventricle constitutes the atrioventricular canal or atrial canal, and indicates the site of the future atrioventricular valves.
