Training mm38131 https://padlet.com/mm38131/8onmwv1nsvc/wish/258356245 There is a training coast off the key of Florida. It's underwater, and astronauts are submerged there for weeks at a time to live in group isolation and carry out experiments and training exercises. Their bodies become fully loaded with nitrogen. Since scuba diving makes them essentially weightless, the astronauts have the opportunity to master the skills and perfect the techniques they will need on space walks. page 237]]> 2018-05-06 23:16:03 UTC https://padlet.com/mm38131/8onmwv1nsvc/wish/258356245 2. Increasing G forces mm38131 https://padlet.com/mm38131/8onmwv1nsvc/wish/258357199 2G- your face droops and your internal organs begin to shift
3G- the liquids in your body become hard to lift; they pool in your legs, and your heart has a hard time pumping them to your head
4G- vision dims because blood flow to the eyes has decreased
more Gs can cause your vision to go completely dark or stop the flow of blood to the brain, page 242]]> 2018-05-06 23:25:44 UTC https://padlet.com/mm38131/8onmwv1nsvc/wish/258357199 3. No gravity environment mm38131 https://padlet.com/mm38131/8onmwv1nsvc/wish/258358058 Respiratory: Your lungs are suffering because of the increased G force; the trachea has been flattened. 
Urinary: The kidneys cannot filter enough blood to make urine. 
Muscular and skeletal: These systems weaken because there is less gravitational force they need to work against. page 244]]> 2018-05-06 23:33:33 UTC https://padlet.com/mm38131/8onmwv1nsvc/wish/258358058 4. Perils of walking outside the space vehicle mm38131 https://padlet.com/mm38131/8onmwv1nsvc/wish/258360274 2018-05-06 23:51:45 UTC https://padlet.com/mm38131/8onmwv1nsvc/wish/258360274 5. Accumulation of expelled carbon dioxide mm38131 https://padlet.com/mm38131/8onmwv1nsvc/wish/258740019 Carbon dioxide is poisonous in high concentrations. Canisters of lithium hydroxide are used to "wash" the CO2 out of the air. Breathing is stimulated by too much carbon dioxide. At toxic levels, your breathing becomes very rapid and shallow, too inefficient to get adequate air into the lungs. page 258]]> 2018-05-07 23:55:21 UTC https://padlet.com/mm38131/8onmwv1nsvc/wish/258740019 6.
