The ventral mesentery is a double-layered membrane that gives rise to the falciform ligament, connecting liver to anterior abdominal wall, the visceral peritoneum of the liver, and the lesser omentum. The ventral mesentery originally stretches between the stomach and the anterior abdominal wall. Also known as the ventral mesogastrium, the portion connecting the liver and stomach becomes the lesser omentum because it attaches along the lesser curvature of the stomach.

The lesser omentum is subdivided into the thin hepatogastric ligament (liver to stomach) and the thick hepatoduodenal ligament (liver to duodenum), along the right edge of the lesser omentum. The hepatoduodenal ligament is thick because it contains large vessels (hepatic arteries and portal vein) and ducts (common bile, cystic, and hepatic).
