(Click here to see the image)

  • Length is 4 m
  • It is situated in the abdominal cavity filling up all the space behind liver and stomach
  • The duodenum begins at the pylorus, passes backwards and upwards first on the visceral face of the liver and then in contact with the right flank to the pelvic inlet
  • Here it turns inwards, passes forwards along the medial aspect of the left colon and at the left kidney bends downward and joins the jejunum
  • The remainder of the small intestine forms numerous coils and attached by the wide mesentery to the sublumbar region
  • The terminal part passes forwards along the medial face of the caecum and opens into the colon at the ileo-colic orifice
  • The bile duct and minor pancreatic ducts open into the duodenum about 5 to 8 cm from the pylorus
  • The major pancreatic duct opens 2.5 cm further back
  • Payer’s patches are numerous, elliptical and the last one is band like and reaches the end of the ileum
