Course Small intestine (anterior view) This seven meter long tube, comprising the duodenum, jejunum and ileum, is the longest portion of the alimentary canal. The small intestine commences its convoluted course through the abdomen at the wider pyloroduodenal sphincter and terminate at the more narrow ileocecal valve.

Gross description. Small intestine is approximately 6 - 7 m in length ( Gastrointest Endosc Clin N Am 2017;27:1 ) Duodenum: Retroperitoneal, except for first part. Common bile duct and pancreatic duct enter the second part of the duodenum at the ampulla of Vater. Suspensory duodenal ligament (ligament of Treitz) divides duodenum from jejunum.

A bulk of the small intestine is suspended from the body wall by an extension of the peritoneum called the mesentery. As seen in the image to the right, blood vessels to and from the intestine lie between the two sheets of the mesentery. Lymphatic vessels are also present, but are not easy to discern grossly in normal specimens.

You are looking at part of the small intestine. The inner surface of the intestinal wall is made of simple columnar epithelium (sce). Instead of being smooth, the inside of the intestine is folded and covered by millions of tiny projections called villi.

The small intestine is composed of four main tissue layers, which are (from outside to centre): Serosa - a protective outer covering composed of a layer of cells reinforced by fibrous connective tissue Muscle layer - outer layer of longitudinal muscle (peristalsis) and inner layer of circular muscle (segmentation)

The small intestine is the site where digestion is completed, using enzymes from the pancreas and bile, and where products of digestion are absorbed. The small intestine possesses several features that increase the surface area for digestion and absorption, including its long length, the presence of plicae circulares, numerous villi, and the simple columnar epithelium with microvilli (brush.

The small intestine is 4-6 metres long in humans. To aid in digestion and absorption: the small intestine secretes enzymes and has mucous producing glands. The pancreas and liver also deliver their exocrine secretions into the duodenum. The mucosa is highly folded. large circular folds called plicae circulares (shown in the diagram to the right.
