 these sections, but the latter is regarded as constituting 

 somewhat more than half the whole. The ileum finally 

 arrives at a point not far from the crest of the right hip- 

 bone and there enters the large intestine. 



The large intestine is so called Trom its diameter, which 

 is two or three times that of the small. It is quite as often 



Fig. 10. The stomach with the pancreas and duodenum: C is 

 placed at the cardiac opening of the stomach, while P is at the 

 pylorus. A dotted line is used to complete the form of the pancreas, 

 which discharges to the intestine near W. The shape of the stomach 

 is of one moderately filled; with further distention the lower border 

 of the organ would sag and the pylorus would cease to be the lowest 

 point. B is the common bile-duct, which reaches the intestine be- 

 hind at the same point at which the pancreas delivers its secretion. 



called the colon. Beginning with a small rounded pouch, 

 the cecum, it may be followed upward on the right side of 

 the body to the level of the lower ribs. This part is the 

 ascending colon. From here it bends sharply to the left 

 and crosses the full width of the abdominal cavity. This 

 horizontal segment is known as the transverse colon and 

 lies close to the ventral body wall. Thus it passes in front 

 of the duodenum and is in practical contact with the
