The percentage of oxygen that we breath in is more than we breath out. The percentage of carbon dioxide is more when we breath out. Nitrogen remains the same because we don't need nitrogen to support our living. Water vapour will also be saturated when we breath out. ]]> 2017-03-22 11:26:02 UTC https://padlet.com/13681513622/lkkwh3tcyw9/wish/161768170 the structure of lung 13681513622 https://padlet.com/13681513622/lkkwh3tcyw9/wish/161770342 2017-03-22 11:36:43 UTC https://padlet.com/13681513622/lkkwh3tcyw9/wish/161770342 Circulatory system and respiratory system 13681513622 https://padlet.com/13681513622/lkkwh3tcyw9/wish/161773065 2017-03-22 11:48:49 UTC https://padlet.com/13681513622/lkkwh3tcyw9/wish/161773065 Inspiration process-step one 13681513622 https://padlet.com/13681513622/lkkwh3tcyw9/wish/161774238 -When we breath in oxygen, external intercostal muscles will contract and internal intercostal muscles will relax and it will cause the ribs rising upwards and downwards.]]> 2017-03-22 11:52:42 UTC https://padlet.com/13681513622/lkkwh3tcyw9/wish/161774238 Inspiration process-step two 13681513622 https://padlet.com/13681513622/lkkwh3tcyw9/wish/161779452 -The diaphragm will also contracts and flattens.]]> 2017-03-22 12:13:09 UTC https://padlet.com/13681513622/lkkwh3tcyw9/wish/161779452 Inspiration process-step three 13681513622 https://padlet.com/13681513622/lkkwh3tcyw9/wish/161780019 -Wether the diaphragm contracts or flattens, the volume inside of the thorax will increase, and ot will cause the pressure inside the thorax to decrease.]]> 2017-03-22 12:15:06 UTC https://padlet.com/13681513622/lkkwh3tcyw9/wish/161780019 Inspiration process-step four 13681513622 https://padlet.com/13681513622/lkkwh3tcyw9/wish/161781863 The atmospheric pressure is higher, air moves into lungs and they inflate]]> 2017-03-22 12:21:39 UTC https://padlet.com/13681513622/lkkwh3tcyw9/wish/161781863 Expiration process-step one 13681513622 https://padlet.com/13681513622/lkkwh3tcyw9/wish/161782387 -When we breath out oxygen, internal intercostal muscles will contract and the external intercostal muscles will relax and it will cause the ribs lowering downwards and inwards.]]> 2017-03-22 12:23:26 UTC https://padlet.com/13681513622/lkkwh3tcyw9/wish/161782387 Expiration process-step two 13681513622 https://padlet.com/13681513622/lkkwh3tcyw9/wish/162007562 -The muscle in the diaphragm will relaxes, and it bulges up due to pressure from the organs below, for example the liver and stomach, and contraction of the abdominal muscles.]]> 2017-03-23 02:25:10 UTC https://padlet.com/13681513622/lkkwh3tcyw9/wish/162007562 Expiration process-step three 13681513622 https://padlet.com/13681513622/lkkwh3tcyw9/wish/162007913 The volume inside of the thorax will decrease, and the pressure of the thorax will increase.]]> 2017-03-23 02:28:25 UTC https://padlet.com/13681513622/lkkwh3tcyw9/wish/162007913 Expiration process-step four 13681513622 https://padlet.com/13681513622/lkkwh3tcyw9/wish/162008188 Elastic recoil of the alveoli helps to force air out of the lungs.]]> 2017-03-23 02:31:05 UTC https://padlet.com/13681513622/lkkwh3tcyw9/wish/162008188 expiration 13681513622 https://padlet.com/13681513622/lkkwh3tcyw9/wish/162058886 2017-03-23 09:47:54 UTC https://padlet.com/13681513622/lkkwh3tcyw9/wish/162058886 inspiration and expitration 13681513622 https://padlet.com/13681513622/lkkwh3tcyw9/wish/162059261 2017-03-23 09:49:32 UTC https://padlet.com/13681513622/lkkwh3tcyw9/wish/162059261
