Document Summary
Upper limits of life of adaptations at high altitude. Lots of radiation w/o food and water for 30 years. Exchange of air in lungs and air outside. Process of a body delivering blood to a capillary bed in tissue. Subunit binding causes conformational change which makes next binding to oxygen easier. Oxygen bonds, binding with co2 is reduced due to conformational shift. The weight of atmosphere, measure with too (mmhg) Atmospheric gases have constant contribution until 11km up. Total p = sum of all partial pressures. Eg at sea level pressure of o is much higher than at altitude. Mountains and all that stuff is in trophosphere. Indoors worker gets 10-20% f uv that outdoor worker yearly exposure. More than 3000m high altitude, 15m world wide people live here. Ancient china, greece, spanish colonist in south america. Depends on speed of ascents and time for acclimatization. Work capacity at 7000m is 40% of that at sea level.
