Liver Development: Ventral Mesentery and Hepatic Lobes

This lecture covers the embryological development of the liver, focusing on the ventral mesentery and the formation of hepatic lobes. Starting with the differentiation of the liver bud in the 5th week, it progresses to the rotation of the stomach and the establishment of ligaments and omenta. The lecture also delves into the vascular segments of the liver, emphasizing the role of the portal vein in defining hepatic segments. Additionally, it discusses the vascularization of liver segments and the surgical implications of the division between the right and left lobes. Detailed descriptions of the ligaments, fissures, and vascular structures of the liver are provided.
