Introduction
Structure
- The ileum is the terminal portion of the small intestine.
- The boundary between the ileum and jejunum is arbitrarily distinguished by the position of the ileocaecal fold.
- It is more muscular and firmer than the jejunum.
- It terminates at the ileocaecocolic junction.
Function
- Mainly absorptive
Vasculature
- The cranial mesenteric artery supplies blood to the ileum.
- see jejunum
Histology
- Peyer's Patches, part of the mucosal associated lymphoid tissue (MALT), are present throughout the ileum and ileocaecal junction.
- They contain B and T lymphocytes.
- B lymphocytes exist in follicles.
