Liquefied food (chyme) exits the stomach and enters the first portion of the small intestine, known as the duodenum. Jejunum means “empty” in Latin and supposedly was so named by the ancient Greeks who noticed it was always empty at death. Stomach This slide shows the structure of the stomach lining under the light microscope. The jejunum is about 0.9 meters (3 feet) long (in life) and runs from the duodenum to the ileum. For example: (Stain - Haematoxylin Eosin) Histology Glossary - Specialised glossary for histology terms and micro-anatomy. The jejunum is a continuation of the small intestine following the duodenum.It begins at the duodenojejunal flexure, where the small intestine turns sharply toward the anterior direction.

The jejunum is the middle of the three parts of the small intestine between the duodenum and ileum.It's arterial supply is provided by the jejunal arteries, while the innervation by the celiac and superior mesenteric plexi together with the vagus nerve. To improve the efficiency of absorption, it is necessary to increase surface area. from the pancreas and gall bladder. Look at slide 162 first. The duodenum is composed of the four layers characteristic of the gastrointestinal tract. Figure 1. It is responsible for the absorption and digestion of nutrients. 1. Slide List. Histology is the study of the microanatomy of cells, tissues, and organs as seen through a microscope. It examines the correlation between structure and function. Mucosa (or mucous membrane) Villi - tall, slender finger-like projections that extend into the lumen. It is the site for the absorption of amino acids, fats, glucose and some large molecules. Duodenum. The three regions of the small intestine are the duodenum, jejunum, and ileum. It plays an important role for digestion as 40% of the whole small intestine is jejunum. Stomach. The histology of the wall of the small intestine differs somewhat in the duodenum, jejunum, and ileum, but the changes occur gradually from one end of the intestine to the other.

Category:Histology - Category listing pages and images associated with histology. The duodenum is the shortest segment of the intestine and is about 23 to 28 cm (9 to 11 inches) long. In the duodenum, chyme is further digested by secretions Duodenum, the first part of the small intestine, which receives partially digested food from the stomach and begins the absorption of nutrients. Begin by identifying the folds of the stomach wall, or rugae, which are visible in a gross specimen.
