The appendix, ileum, and ascending colon are all derived from the midgut. The appendix first appears at the 8th week of gestation as a downward out-pouching of the caecum and gradually rotates to a more postero-medial location as the gut rotates and the caecum becomes fixed in the right lower quadrant.
