The intestines are the convoluted membranous tube which extends from the stomach to the anus and which receives the ingested food from the stomach, mixes it with bile, pancreatic juice and intestinal secretions, gives origin to the chyle and delivers the indigestible products from the system. The intestines are divided into the small and large intestine (colon). The small intestine is further divided into three parts: the duodenum, the jejunum and the ileum. The large intestine is divided into the ascending colon, the tansverse colon, the descending colon and the rectum that terminates at the anus. Research Intestines
