Liver in situ

This video tutorial explores the anatomy of the liver in situ, focusing on its lobes, functions, and surrounding structures. It covers the liver's role in detoxification, protein synthesis, and nutrient storage. The tutorial also examines the pancreas, spleen, gallbladder, esophagus, duodenum, and various ligaments and peritoneal structures. The content is designed to provide a comprehensive understanding of the liver's anatomical relationships within the abdomen.
