  1. The Diaphragm By Jeff Baldwin, Frankie DiGisi & Meg Hislop http://www.dkimages.com

  2. Cardiovascular System http://www.ama-assn.org

  3. Diaphragm • Moves down for inhalation • Moves up for exhalation • Pressure gradient http://oac.med.jhmi.edu/

  4. Pressure Gradient • Lower pressure, air enters the lungs • Higher air pressure, air leaves the lungs • Pressure equilibrium Biology: The Unity and Diversity of Life

  5. Thoracic Cavity • Protective cover • Space for expansion • Volume changes • Increase and decrease in size helps create pressure gradient http://www.templejc.edu/
