  • large plicae circulares
  • thicker wall

Ileum—

  • shorter vasa rectae
  • smaller plicae circulares
  • thinner wall (Think: Ileum= Inferior vasa rectae, Inferior plicae circulares, and Inferior wall)

A

Colon has taeniae coli, haustra, and appendices epiploicae (fat appendages),whereas the small intestine is smooth
