False-colour scanning electron micrograph (SEM) of the wall of the large intestine (colon), showing two goblet cells. Goblet cells (brown) are mucous secreting cells. Here, they occur among the micro- villi of absorptive cells. The colon functions to absorb water and remaining nutrients from digested food faeces. Microvilli on absorptive cells increase the colon surface area for this purpose. The mucous secreted by goblet cells lubricates the passage of faeces, protecting the colon wall from mechanical damage; it also enables faeces to pass closely over absorptive cells to assist with absorption. Magnification: x3,450 at 6x7cm size. Magnification: x5,550 at 4x5 inch size.
