- n. In anatomy, the lower part of the alimentary canal, extending from the pyloric end of the stomach to the anus; gut; bowel: in popular use usually in the plural: the guts; bowels; entrails. In a wider sense, in biology, the term is also used to include the whole alimentary canal or enteron. (See
alimentaryand enteron.) In man, as in other vertebrates and many invertebrates, the intestine is the tube into which partly digested food is received from the stomach, for the completion of the digestive process by the action upon the food of certain secretions (as the hepatic, pancreatic, and intestinal), the drawing off of the assimilable material by the blood-vessels and lacteals, and the ejection of the refuse or non-assimilable substances, as feces or excrement, by the anus. The length of the human intestine is five or six times that of the body, such extent representing, perhaps, an average of relative length; the intestine is generally shorter in carnivorous animals, and longer in those which are herbivorous. It is a museulomembranous tube invested with a peritoneal coat, lined with mucous membrane, and having in its walls both longitudinal and circular muscular fibers. It lies coiled in many convolutions in the abdomen, the coils being freely movable, though the tube as a whole is held in place by mesenteric folds of peritoneum. Into it are poured the secretions of the liver and pancreas, as well as those Of its own numerous glandular structures. The character of the tube in man and mammals generally has caused its division into a small and a large intestine. The former extends from the pylorus to the iliocæcal valve, and is subdivided into duodenum, jejunum, and ileum. The latter consists of the cæcum or head of the colon, with its appendix vermiformis; of the colon proper, divided into ascending, transverse, and descending; and of the rectum or straight gut, continued from the descending colon by the sigmoid flexure. The small intestine is smoothly and simply tubular; the large is more or less extensively sacculated. This distinction does not hold as a rule below mammals, in many of which, also, the cæcum is of comparatively enormous extent. Thus, in birds, in which there are commonly a pair of cæca, the site of these organs marks the only distinction between the preceding and succeeding portions of the tube. In many lower vertebrates, as fishes, cæca may be very numerous, and situated near the pylorus. In all vertebrates the cavity of the intestine is primitively continuous with that of the umbilical vesicle, and in those which have an allantois with the cavity of that organ. In its simplest possible form the intestine represents the interior of a gastrula. See cut under gastrula.

“This bowel tube, or intestine, which, on account of its length, is arranged in coils, finally delivers the undigested remains of the food into a somewhat larger tube called the _large intestine_, in the lower and back part of the body, where its remaining moisture is sucked out of it, and its solid waste material passed out of the body through the _rectum_ in the form of the _feces_.”
“A congenital defect in which part of the intestine is completely blocked or absent.”
“Your intestine is long and pocketed unlike meat eating animals where it is short and smooth, your teeth are not designed for ripping and chewing carcass, you have no claws, nor speed that is why you have to purchase thousands of dollars worth of equipment such as tree stands, bait, lures, fake female, "buck in heat" and of course the weapon to do your killing.”

“She had intestinal blockage and had a nasty upper-respiratory infection when she was nine weeks old, and when they spayed her at Bide-a-Wee, they also cleared the blockage, which means her intestine is shortened, so she has to eat special food.”
“The secretion of the above-mentioned special intestinal ferment by the wall of the intestine is solely due to the stimulating action of the pancreatic protein ferment.”
“Then the stomach is a simple sac, undivided into compartments, and the intestine is short, not more than three times the length of the body, instead of being some twenty times longer, as in some herbivores.”
