Description: Examines the respiratory systems in various types of animals, demonstrating the evolution of transport systems for movement of materials in larger animals. Shows the movement of oxygen and carbon dioxide across a moist, permeable membrane in paramecia; the spiracles and tracheal system of grasshoppers; and the gills of the axolotl, clam, crayfish, and fish. Uses a dissected fetal pig to show the channeling of air to the lungs, followed by X-ray photography of the breathing movements of the rib cage and diaphragm in a human.
