THE SMALL INTESTINE

The duodenum is also arranged rather like that of the dog, descending toward the pelvis before turning to run forward to the left of the root of the mesentery before dipping ventrally to be continued by the jejunum (Figure 34-7/7,2,3).

The jejunum is arranged in many small loops (Figure 34-9/4) suspended by a mesentery that gives them much freedom of position (Figure 34-7/11). The greater part lies in the right half of the abdomen, ventrally and toward the pelvis, but some part may be in contact with the left flank behind the colic spiral. Like many other abdominal organs, the jejunum must accommodate its position to the condition of the stomach and, in sows, to that of the uterus.
