The serous coat has nerve plexuses. There are columnar epithelium and goblet cells, with smooth muscle in folds at the base. The '''caecal sphincter''' at the proximal part contains a lot of lymphoid tissue. (caecal tonsil) The middle section has thin walls and appears green and the bulbous blind ends have thicker walls.
