Greater omentum

The video tutorial explores the greater omentum, a significant fold of visceral peritoneum in the abdominal cavity. It begins with an introduction and orientation, followed by a detailed explanation of its structure, including its layers and appearance. The tutorial then discusses the functions of the greater omentum, highlighting its role in fat deposition and infection control, earning it the nickname 'policeman of the abdomen.' The blood supply, derived from the gastroepiploic arteries, and its venous drainage are covered. The video also examines the relations and associated structures, such as the liver and intestines, and concludes with clinical notes on conditions like omentectomy.
