How the Body Works : The Stomach
The Stomach The stomach acts as a reservoir for food and has a capacity of two and a half pints. Within the stomach, solid food material is churned and kneaded for about three hours until it becomes a semiliquid mass known as chyme. The chyme is then forced into the small intestine, where the process of digestion is completed. The wall of the stomach has three muscular layers, an outer longitudinal layer, a middle circular layer and an inner oblique layer. As the stomach fills with food, wavelike contractions of the wall begin, and as these waves move along the stomach wall some of the food is passed through the relaxed muscle valve at the base and into the duodenum, the first part of the small intestine, where it is further digested before being absorbed into the body.
How the Body Works : The Small Intestine
The Small Intestine The small intestine, a twenty-one-foot tube, lies in coils in the abdomen. The first ten to twelve inches are called the duodenum, which is the U-shaped section of the small intestine that joins the stomach and the jejunum. The next eight feet, the jejunum and the remaining twelve feet the ileum, join the duodenum with the large intestine. The muscle layers of the small intestine are arranged longitudinally on the outside and circularly on the inside. Between the muscle layers are a series of nerve fibers which control the muscular movements that mix and move food along. The common bile duct is the opening through which bile and pancreatic juices enter the small intestine. As food reaches the duodenum from the stomach, it is mixed with these juices and further digested. At the base of the duct is a ring of smooth muscle, the sphincter, which regulates the outflow of fluid. Digested food is absorbed into the cells through the fingerlike projections lining the small intestine called the villi. The Crypts of Lieberkuhn, numerous tubular glands which open into the intestine from between the villi, secrete an alkaline fluid rich in digestive enzymes and mucus. The mucus protects the tissues of the small intestine from being digested by it’s own enzymes. Brunner’s glands pour out an alkaline juice to neutralize the acid chyme reaching the small intestine and to create the necessary conditions for further digestion. Tributaries of the portal vein carry …
