In the human embryo, the vitelline duct, also known as the vitellointestinal duct,[1] the yolk stalk,[1] the omphaloenteric duct,[1] or the omphalomesenteric duct,[1] is a long narrow tube that joins the yolk sac to the midgut lumen of the developing fetus.[2] It appears at the end of the fourth week, when the yolk sac (also known as the umbilical vesicle) presents the appearance of a small pear-shaped vesicle.
