Jejunum vs ileum

Dr Henry Knipe et al.

There are a few differences that can help differentiate jejunum and ileum 1-3:

  • jejunum is slightly wider (< 3 cm) than ileum (<2 cm)
  • jejunum folds (valvulae conniventes) are thicker (2-3 mm) than ileum folds (1-2 mm)
  • jejunum folds are also more numerous and deeper than ileum folds
