430 DIGESTIVE SYSTEM OF THE HORSE flexure of the great colon; ventrally to the bladder (when full) or to the uterus,. The second part of the rectum is related dorsally and laterally to the pelvic wall. Ventrally the relations differ in the two sexes. In the male they are the bladder, the terminal parts of the ductus deferentes, the vesicute seminales, the prostate, the bulbo-urethral glands and the urethra. In the female they are the uterus, vagina, and vulva.^ Structure of the Large Intestine The serous coat covers the different parts in varying degree. It does not cover (a) the opposed surfaces of the cfficum and colon which are between the layers

The muscular coat consists of longitudinal and circular fibers. The bulk of the former is in the bands of the caecum and colon. It is to be noted, however, that the bands of the caecum and the ventral parts of the great colon are largely composed of elastic tissue. The bands of the dorsal parts of the colon are largely muscular, and those of the small colon are almost entirely muscular. Some of the circular fibers pass from one part of the colon to another, where they are attached to each other, forming the fibrse transversae coli. The muscular coat of the ampulla of the rectum presents special features. The longitudinal layer of fibers is very 1 The anterior part of the rectum is variable in position and relations. The amount covered by peritoneum dorsally and laterally is very variable, and appears to be in inverse proportion to the fulness of the bowel.
