Small Intestine

The small intestine (also known as small bowel), connecting the stomach and the large intestine, is a winding and tightly folded tube of the gastrointestinal tract. It bears the work of further digestion of the food from stomach and absorption of nutrients from these foods. The small intestine is comprised of three distinct parts: the duodenum, jejunum, and ileum. The shortest duodenum part is the start of the small intestine which receives bile and pancreatic juice through the pancreatic duct for chemical digestion. The jejunum is follow up with the duodenum and is where the most absorption of food takes place. The last segment of small intestine is the ileum. It bears further absorption of the remaining nutrients before moving into the large intestine. As a digestive organ dealing with the food and drink from outside, the small intestine problems arise more easily, such as inflammations, infections, bleeding, or even cancers. The small intestine tissue is commonly applied in immunohistochemical detection by targeting a variety of biomarkers on it.
