For example,the small intestines are supplied by the superior mesentericartery (Pig.

The transverse and ascend-ing portions of the colon and ccecum are supplied by thecolica media (11), colica dextra (14), and ilio-colica (15), givenoff from the opposite side of the vessel; while the descendingcolon and rectum are supplied by the inferior mesentericartery (Fig. 112, 9), the superior hemorrhoidal (13) descendingas low as the middle of the sacrum, where it divides into two
