intestine
(in-tes“tin)
the part of the alimentary canal extending from just below the stomach to the anus; it is a membranous tube and is divided into the small intestine and the large intestine. Called also bowel and gut.
large intestine
the lower part of the intestinal tract, which starts just below the ileum and is about 1.5 meters long. Here the liquid waste from the small intestine is formed into more or less solid feces for discharge through the rectum. The parts of the large intestine are the cecum, the colon (with ascending, transverse, descending, and sigmoid parts), and the rectum.
small intestine
the upper part of the intestinal tract, consisting of the duodenum (connected to the stomach), the jejunum, and the ileum (connected to the large intestine). It is small in diameter but very long (over 6 meters). The digestion of food is completed here; digested food is absorbed
through the walls of the small intestine into the blood, and indigestible parts of the food pass along into the large intestine.
