YukiMorikubo https://padlet.com/YukiMorikubo/ptohpncrj691/wish/160405847 It occurs when we are breathing. There's a change of pressure in the lungs to help us breath in and out the air called ventilation. 
This process include inspiration and expiration. ]]> 2017-03-16 01:11:05 UTC https://padlet.com/YukiMorikubo/ptohpncrj691/wish/160405847 Inspiration YukiMorikubo https://padlet.com/YukiMorikubo/ptohpncrj691/wish/160406713 1. When the inspiration occurs, our external intercostal muscles contract and the internal intercostals muscles relax. 
2. The diaphragm contracts and flattens. 
3. These actions increase the volume inside the thorax, and the pressure decrease. 
4. The air have larger pressure than the pressure inside the thorax, so the air will go in to the lungs. 
5. This make the inspiration occurs and breathe in the oxygen. ]]> 2017-03-16 01:18:35 UTC https://padlet.com/YukiMorikubo/ptohpncrj691/wish/160406713 Expiration YukiMorikubo https://padlet.com/YukiMorikubo/ptohpncrj691/wish/160407704 1. When the expiration occurs, our external intercostal muscles relax and the internal intercostals muscles contract. 
2. The diaphragm relax and the ribs lower downwards and inwards.
3. This decrease the volume and the pressure increase inside the thorax. 
4. The air will go out of the lungs. 
5. This make the expiration occurs and breathe out the oxygen. ]]> 2017-03-16 01:26:47 UTC https://padlet.com/YukiMorikubo/ptohpncrj691/wish/160407704 YukiMorikubo https://padlet.com/YukiMorikubo/ptohpncrj691/wish/161043643 2017-03-20 00:34:01 UTC https://padlet.com/YukiMorikubo/ptohpncrj691/wish/161043643
