Week 6 - Human Digestive Tube

The primitive mesentery of a six weeks’ human embryo, half schematic. (Kollmann)


The stomach undergoes a further dilatation, and its two curvatures can be recognised (Figs. 983, B, and 984), the greater directed toward the vertebral column and the lesser toward the anterior wall of the abdomen, while its two surfaces look to the right and left respectively.

Behind the stomach the gut undergoes great elongation, and forms a V-shaped loop which projects downward and forward; from the bend or angle of the loop the vitelline duct passes to the umbilicus (Fig. 984).
