THE INTESTINE 487 and numerous large lymph glands at its root; the root is attached in the sublumbar region behind the stomach and blends here with the mesentery of the large intestine. The mesenteric part is arranged in close coils and lies mainl}' above the colon and cfficum, from the stomach to the pelvis; many coils lie against the right flank and on the posterior part of the floor of the abdomen. The opening of the bile duct is about one or two inches (ca. to 5 cm.) from the pylorus, and that of the pan- creatic duct about six inches (ca. 15 cm.) beyond it. Aggregated lymph nodules or Peyer's patches and solitary nodules are numerous and very distinct. The patches are usually band-like aiul prominent; their number has been found to vary from 16 to 38. They begin 8 to 20 inches (ca. 20-50 cm.) from the pylorus. The last long one is continued a variable distance in the caecum. The solitary nodules. Fig. 427.—Cecum .^.nd Colon or Pio: Left V 1, Apes of spiral coil of colon; 2, apes of are distinct (except in the duodenum), but are only about a millimeter high. The duodenal glands extend some 10 to 16 feet (ca. 3-5 m.) from the pylorus. The large intestine is about 12 to 15 feet (ca. 4 to meters) in length, and is for the most part much wider than the small intestine; it is connected by a mesen- tery with the ilorsal abdominal wall between the kidneys. The caecum is cylin- Idrical, about 8 to 12 inches (ca. 20 to 30 cm.) long, and 3 to 4 inches (ca. 8 to 10 cm.) l^-ide. It lies against the upper and anterior part of the left flank, and extends jventrally, backward, and medially behind the coiled part of the colon, so that its Iventral blind end usually lies on the floor of the abdomen, near the median plane, land at a variable point between the umbilicus and the pelvic inlet (Fig. 423). Its porsal end is directly continued by the colon, the line of demarcation being indi- ated by the termmation of
