Anatomy of small intestine

  • The small intestine is located in the abdomen

  • The upper end is connected to the pylorus of the stomach

  • The lower end is connected to the large intestine

  • total length is about 4-6 meters

  • Main place for food digestion and absorption 

  • Digestion in the small intestine 

    • chemical digestion: pancreatic juice, bile and small intestinal juice

    • mechanical digestion: small intestinal movement

  • nutrients are absorbed by the small intestinal mucosa

  • Divided into three parts: duodenum, jejunum and ileum


  • Duodenum

    • The upper end of the duodenum starts from the pylorus

    • the lower end is on the left side of the second lumbar vertebral body, and continues to the jejunum

    • It is about 25-30 cm long and surrounds the head of the pancreas in the shape of a horseshoe

    • Has 4 parts: superior part, descending part, transverse part, and ascending part

    • There is a common opening of the common bile duct and pancreatic duct on the posterior medial wall of the descending part of the duodenum, through which bile and pancreatic juice flow into the small intestine



  • Jejunum 

    • jejunum makes about 2/5 of the total length of the small intestine

  • Ileum

    • The ileum occupies the distal 3/5 of small intestine. 

    • There is no obvious boundary between the jejunum and the ileum

    • There is a gradual change in morphology from jejunum to ileum.
