Inhale, the diaphragm moves downward, the chest volume becomes larger, the lungs pressure below atmospheric pressure, the external air pressure to the air into the lungs
During exhalation（呼气）, the diaphragm moves upward, the volume of the thoracic cavity becomes smaller, and the internal pressure is greater than the outside]]> 2017-03-23 13:25:25 UTC https://padlet.com/2653387865/n8r59hdocorx/wish/162117008 2653387865 https://padlet.com/2653387865/n8r59hdocorx/wish/162124774 2017-03-23 13:44:02 UTC https://padlet.com/2653387865/n8r59hdocorx/wish/162124774
