Duodenum - Anatomy and Function

Explore the anatomy and function of the duodenum, the first segment of the small intestine, in this 15-minute educational video. Learn about the duodenum's crucial role in digestion and nutrient absorption, examining its anatomical structure, key physiological functions, and distinctive histological features. Discover how this C-shaped portion of the small intestine receives digestive enzymes from the pancreas and bile from the liver, facilitating the breakdown and absorption of nutrients from food. Study the duodenum's four anatomical parts - superior, descending, horizontal, and ascending portions - and understand their specific contributions to the digestive process. Examine the microscopic structure including the intestinal villi and crypts that maximize surface area for absorption, and learn about the specialized cells that line the duodenal wall. Understand the duodenum's relationship with surrounding organs including the pancreas, liver, and gallbladder, and how these connections enable efficient digestion and metabolism.
