Jejunum - 1 to 2 m long, coiled mid-section of the small intestine. The organ that is part of the small intestine and follows the duodenum.
The final stages of digestion are completed in this portion of the small intestine, where foods and liquids are fully broken down into their nutrient components such as:
Since the digestive tract is long and tube-like, it is generally susceptible to other problems common with tube-shaped organs. Some of the worst problems are usually blockages where the food can not get through the Jejunum and into the next organs. Common reason for blockages are inflammation of either the Jejunum or nearby organs, or from an external blow. Other problems may be scarring of the walls that line the Jejunum, making it harder for food to get through.
Since most of the digestion of nutrients happens in the small intestine and the duodenum is responsible to much of the protein absorption, the jejunum is an important part of the digestive tract. To spot problems with the greater digestive system or the small intestine in particular you may want to be mindful of your stools during defecation. As an example, blood in stools that is not well mixed in with the stools and has retained most of its red color is likely a sign of bleeding towards the bottom of the end of the cycle since the blood had not had a chance to decay.
The descending colon is very close to the bottom of the Digestive Tract and is one of the parts of the colon. Here are all the parts of the colon:
