LARGE INTESTINE (FOWL)

  • The large intestine consists of the two caeca and the colon. The line of demarcation between the ileum and the colon is at the openings of the caeca
  • The caeca are two in number, left and right and are two blind tubes about 16 to 18 cm long extending from the ileo-colic junction on either side of it, forwards to the liver and are doubled on themselves
  • They are connected with the gastro-intestinal tract at the junction between the ileum and colo-rectum
  • Each of these tubular structures has a length of about 15cm
  • They extend first cranially and then caudally parallel to the ileum
  • Each caecum has three parts-proximal, middle and distal
  • The proximal part is narrow and is connected with the intestine. Middle part is wide and the distal part is expanded
  • The distal part terminates in the form of a pointed end. The wall contains lymphoid tissue, mostly at the proximal part. This lymphoid tissue is known as caecal tonsil
  • The colon or colo-rectum is short straight tube, (without any demarcation between colon and rectum), extending backwards from the openings of caeca, to terminate behind at the cloaca. (View image)
