1. the intercostal muscle first contract, then the ribs goes up
2. the diaphragm contract and moves down.
3.thus the volume of thorax increase and the pressure inside it start to drop
4. after it is below the atmospheric pressure, the air came in and through mouth, trachea, bronchi and bronchioles, then go into the lungs.]]> 2017-03-16 01:31:15 UTC https://padlet.com/sunnyhuang0104/7vjqsy3wxfp8/wish/160408326 Expiration: sunnyhuang0104 https://padlet.com/sunnyhuang0104/7vjqsy3wxfp8/wish/161451764 Expiration is a movement of the air go out of the body. during this process, 1. the intercostal muscle contract, and the ribs moves down
2. the abdominal muscle contract and push diaphragm up.
3.  it will be a result of a decrease in volume of thorax, and the pressure inside increases
4. ultimately the pressure rises above the atmospheric pressure, then the air flow out of the lungs, and came out through mouth or nose.]]> 2017-03-21 11:50:18 UTC https://padlet.com/sunnyhuang0104/7vjqsy3wxfp8/wish/161451764
