THE SMALL INTESTINE. 



Describe the Small Intestine. It is a convoluted, tubular, digestive 

 organ, about 20 feet in length, held to the spinal column by the mesenteric 

 portion of the peritoneum, and divided into 3 parts, the 



Duodenum, about 12 fingers (10 inches) long, ascends for 2^ inches to 

 p the under surface of the liver and the 



neck of the gall-bladder, descends 

 for 3^ inches in front of the right 

 kidney, and passes transversely for 4 

 inches to the left, across the spinal 

 column, to the left side of the second 

 lumbar vertebra, where the superior 

 mesenteric artery crosses its junction 

 with the jejunum. The duodenum 

 has no mesentery, is partially covered 

 with peritoneum, and surrounds the 

 head of the pancreas. Into its descending portion open the ductus 

 communis choledochus/ and the pancreatic duct. 



fejunum, about two- fifths of the rest of the small intestine, its coils lying 

 around the umbilical region. It is named from the fact that it is tsually 

 found empty (jejunus) after death. 



Ileum, comprises the remainder of the small intestine ; is named from its 

 twisted course, lying below the umbilicus, and terminating in the right 

 iliac fossa, at the ileo-csecal valve, or valve of Bauhin. 

 What Coats has the Small Intestine ? Three, a mucous, a sub-mucous 

 or cellular, and a muscular coat. Its peritoneal investment is sometimes da- 

 scribed as a fourth coat, but incorrectly. The
