The narrow, winding, upper part of the intestine where digestion is completed and nutrients are absorbed by the blood. It extends from the pylorus to the cecum and consists of the duodenum, the jejunum, and the ileum. the long tube that food goes through after it has gone through your stomach large intestine. Long, narrow, convoluted tube in which most digestion takes place. It extends 22-25 ft (6.7-7.6 m), from the stomach to the large intestine. The mesentery, a membrane structure, supports it and contains its blood supply, lymphatics, and insulating fat. The autonomic nervous system supplies it with parasympathetic nerves that initiate peristalsis and sympathetic nerves that suppress it. It is lined with minute fingerlike projections (villi) that greatly increase its surface area for enzyme secretion and food absorption. Its three sections, the duodenum, jejunum, and ileum, have distinct characteristics. Food takes three to six hours to pass through the small intestine unless a disorder such as gastroenteritis, diverticulosis, or obstruction impedes it
the section of the digestive tract between the stomach and the large intestine Most of digestion occurs here as nutrients are absorbed from food
part of the digestive tract comprised of the duodenum jejunum and ileum, primary organ for absorbing digested nutrients into the body
The small intestine is divided into the duodenum, jejunum, and ileum It is here that most of the processes of digestion and absorption of food take place
n The part of the intestine (consisting of sections called the duodenum, jejunum and ileum) that lies between the stomach and colon It secretes digestive enzymes and is the chief site of the absorption of digested nutrients The total length of the small intestine is approximately 22 feet
The part of the digestive tract that extends from the stomach to the large intestine The small intestine includes the duodenum (closest to the stomach), the jejunum, and the ileum (closest to the large intestine)
The part of the digestive tract where food passes from the stomach and is broken down into nutrients that the body can absorb and use
