It was help us to breathing that make sure we can in life.]]> 2017-03-23 09:46:49 UTC https://padlet.com/19zhangjing/x5ybqse67uxw/wish/162058610 19zhangjing https://padlet.com/19zhangjing/x5ybqse67uxw/wish/162058701 1.  When we inhale, the external intercostal muscles was contract, in other way the internal intercostal muscles was being relax. Also the ribs will raising to the upwards and outwards.
2. Diaphragm is between the chest cavity and abdominal cavity. It will follow with your body, when you breathing (contracts and flatten).
3. Structure of the thorax is 12 thoracic, 12 ribs, 1 sternum and intercostal muscles. When you start to inhale, it will increases the diameter of the thorax. Of course, exhale when doing the opposite direction of movement, so that the chest volume will decreased.
4. The atmospheric pressure is grater, when air moves it will into your lungs and they inflate, that make your lungs have air.]]> 2017-03-23 09:47:08 UTC https://padlet.com/19zhangjing/x5ybqse67uxw/wish/162058701 19zhangjing https://padlet.com/19zhangjing/x5ybqse67uxw/wish/162058789 1.  When you expiration, that have opposite action with inspiration. That means your internal intercostal muscles contract and external intercostal muscles will be relax.
2. Expiration that make your ribs be lower and inwards and downwards.
3. The diaphragm will be relax and rises. 
4. The thoracic cavity volume decreases, causing the the lungs to recoi.
5. The intrapulmonary volume decreases. This causes the intrapulmonary pressure to rise, and the air flows out of the lungs until the intrapulmonary pressure equals the atmospheric pressure.]]> 2017-03-23 09:47:29 UTC https://padlet.com/19zhangjing/x5ybqse67uxw/wish/162058789 19zhangjing https://padlet.com/19zhangjing/x5ybqse67uxw/wish/162064755 2017-03-23 10:10:41 UTC https://padlet.com/19zhangjing/x5ybqse67uxw/wish/162064755 19zhangjing https://padlet.com/19zhangjing/x5ybqse67uxw/wish/162065234 Image: https://image.baidu.com/search/detail?z=0&ipn=d&word=lungs&step_word=&hs=0&pn=1&spn=0&di=181936683500&pi=&tn=baiduimagedetail&is=0%2C0&istype=0&ie=utf-8&oe=utf-8&cs=39017599%2C1486375272&os=409806089%2C4036726815&simid=&adpicid=0&lpn=0&fm=&sme=&cg=&bdtype=0&simics=1466191216%2C3446480043&oriquery=&objurl=https%3A%2F%2Ftimgsa.baidu.com%2Ftimg%3Fimage%26quality%3D80%26size%3Db10000_10000%26sec%3D1490263778%26di%3D6280fc8f19e7f5b64097bb2645817ed9%26src%3Dhttp%3A%2F%2Fi1.wp.com%2Fwww.philipcaruso-story.com%2Fwp-content%2Fuploads%2F2015%2F12%2FCystic-fibrosis.jpg&fromurl=ippr_z2C%24qAzdH3FAzdH3Fooo_z%26e3Britstrvw67f5-fp56y_z%26e3Bv54AzdH3Fvyfptv-utk65ftfAzdH3F&gsm=0&cardserver=1
