Without the gravity that pools the blood to the peripheries it may be important to consider how our vascular pressures are altered to affect the diffusion of CO2 into the brain ...

So, if more blood is goes to the brain, and more CO2 is directed to the brain, will we have more of a tendency to hyperventilate during space travel?]]> 2018-03-15 13:10:58 UTC https://padlet.com/alexavstar/t2f9f1vwwkja/wish/242327655 Long term effects alexavstar https://padlet.com/alexavstar/t2f9f1vwwkja/wish/242331361 Will prolonged stay in space have an effect on the sensitivity of a certain group of chemoreceptors?]]> 2018-03-15 13:16:26 UTC https://padlet.com/alexavstar/t2f9f1vwwkja/wish/242331361 12mjg12 https://padlet.com/alexavstar/t2f9f1vwwkja/wish/242335230 2018-03-15 13:22:12 UTC https://padlet.com/alexavstar/t2f9f1vwwkja/wish/242335230
