  • Villus | Structure, Function Location | Britannica
    Important villous membranes include the placenta and the mucous-membrane coating of the small intestine The villi of the small intestine project into the intestinal cavity, greatly increasing the surface area for food absorption and adding digestive secretions
  • Intestinal villus - Wikipedia
    Villi are specialized for absorption in the small intestine as they have a thin wall, one cell thick, which enables a shorter diffusion path They have a large surface area so there will be more efficient absorption of fatty acids and glycerol into the blood stream
