Anatomy - Hepatic Portal Circulation EXPLAINED

The video explains hepatic portal circulation, focusing on the liver's role in nutrient distribution. It covers the anatomy of the hepatic portal vein and related vessels, detailing how nutrients from the digestive system are absorbed and transported to the liver. The video also discusses the roles of the stomach and spleen in this process, and concludes with a model demonstration to visualize the circulation system.
