The liver originates from the foregut portion of the primitive gut as an outgrowth called the hepatic diverticulum from the ventral foregut endoderm. This hepatic bud forms around week 3–4 and grows into the surrounding mesoderm of the septum transversum to become the liver parenchyma and biliary system. The foregut includes structures like the esophagus, stomach, liver, gallbladder, biliary tree, and proximal duodenum, so the liver is a foregut derivative. The hindgut and midgut produce other portions of the gut, not the liver, and the dorsal mesentery is a peritoneal structure rather than a gut region. Hence, the liver develops from the foregut.
