      1. Intercostal Muscles and Diaphragm contract
        1. Thorax volume increase
          1. Pressure decrease
            1. Air drawn in
          2. Breathing Out
            1. Intercostal muscles and Diaphragm relax
              1. Thorax volume decreases
                1. Pressure increses
                  1. Air pushed out
              2. Artificial Ventilators
                1. Iron Lung
                  1. Neck to abdomen
                    1. Air pumped out
                      1. Presuure decreases
                        1. Lungs expand
                          1. Air drawn in
                  2. Ventilators
                    1. Pump air into lungs
                      1. Air released when pumping stops
                  3. Location and Organs
