Content: There is a thin membrane called the mesentery that surrounds the small intestine and anchors it in place. Many blood vessels, lymphatic vessels, nerves pass through the mesentery. They provide support to the tissues of the small intestine and also help in the transport of nutrients from intestines to the rest of the body. The small intestine is divided into three regions: Duodenum- It is the first section which connects to the pyloric sphincter of the stomach. It is the shortest region of the intestine. The chyme gets mixed with bile and pancreatic juice here. Jejunum – It is the middle section and is the primary site of nutrient absorption. This region measures around 3 feet in length. Ileum – It is the final section of the small intestine that empties into the large intestine.
