Introduction

Structure

  • The caecum is a blind-ending diverticulum of the large intestine.
  • It communicates with the ileum via the ileal orifice and with the colon via the caecocolic orifice.
  • It consists of a base, body and apex, the apex being the blind-ending portion.
  • It is attached to the ileum by a fold of peritoneum called the ileocaecal fold.
