   {Large intestine} (Human Anat. & Med.), the lower portion of
      the bowel, terminating at the anus. It is adapted for the
      retention of fecal matter, being shorter, broader, and
      less convoluted than the small intestine; it consists of
      three parts, the c[ae]cum, colon, and rectum.

   {Small intestine} (Human Anat. & Med.), the upper portion of
      the bowel, in which the process of digestion is
      practically completed. It is narrow and contorted, and
      consists of three parts, the duodenum, jejunum, and ileum.
