1. When we do expiration, our ribs will move downwards and inwards.
2. Internal intercostal muscles will expend and external intercostal muscles will relax.
3. The volume in lungs will decrease, and our diaphragm relax.
4. It will decrease the volume of the lungs and the pressure will increase.
5. When air out of body, the elastic recoil of the lungs help our body to force air out the body, it can also help to get waste out of our lungs.

1. When we breathing in oxygen, our diaphragm will moves down.
2. Our external intercostal muscles will shrink and the internal intercostal muscles will relax.
3. The volume inside the thorax will increase, the air will though epiglottis which control water and food did not go in to the trachea.
4. At same time the pressure of lungs will start decrease.
5. The atmospheric pressure will be greater, the air will through bronchus to lungs, bronchiole and alveoli.

Venntilation require pressure changes to occur in the lungs,so that air can be forced in an out of the alveoli.
