      Lungs. An animation showing structure of lungs and gas exchange. Note that all tissues: lungs, alveoli, blood capillaries, red blood cells, etc. are all constructed from cells that have grown and differentiated in special ways.

      Intestines. A video showing cellular structure with animation of food being absorbed from intestine into blood. The film includes much technical terminology, which can be ignored while maintaining a focus how structure facilitates function.

      Nervous system. Cellular structure and function animation

      Muscle. Muscle cells have a very complex structure that enables their function of contraction. Again, technical terminology can be overlooked.
