Across
  1. 7. The reason why track and field records are broken at high altitude is because of the low wind ____ and thin air
  2. 8. This is one of the body's primary immediate response to large elevation change characterized by breathing deeply and fast
  3. 9. This altitude stress is a condition in which the body is at a decrease in water content from altitude
  4. 11. Transfer of heat from a body to an object,about 3% of total heat loss at room temperature occurs this way
  5. 13. Breakdown of muscle fibers that causes the release of myoglobin into the bloodstream, and that myoglobin can cause kidney damage.
  6. 15. This is a pressurized chamber to mimic different levels of atmospheric pressure. ______ chamber
  7. 17. At greater than 20% of this, the skin cracks and bleeds
  8. 19. This process is the conduction of heat to air or water.
  9. 20. About 25% of heat is lost this way in a comfortable environment, and sweat is only effective through this process
Down
  1. 1. Caused by ice crystal formation within the tissue,occurs in exposed skin and Can lead to tissue death.
  2. 2. This altitude stress is characterized by a loss of heat faster than body can produce heat
  3. 3. This heat illness results from acute plasma volume loss and inability of the circulation to compensate for the concurrent vasodilation in the skin and the active working muscles. The person cannot participate in activity for the rest of the day.
  4. 4. This altitude stress is characterized by a lack of oxygen at the tissue level of the body
  5. 5. This altitude stress is a condition of irregular nighttime breathing, like holding your breath and finally breathing (2words,no space)
  6. 6. This sickness is caused by high partial pressures of nitrogen,occurs at about 30 meters or 100 feet.
  7. 10. Occurs when the body becomes unable to control its temperature: the body's temperature rises rapidly, the sweating mechanism fails, and the body is unable to cool down.
  8. 12. This altitude stress is a condition of abnormally low blood glucose, less than 70 mg/dl
  9. 14. This is also called decompression sickness,and is caused by a nitrogen bubble formation in the tissue due to too rapid of an ascent.
  10. 16. Loss or gain in the form of electromagnetic waves,at rest, in a comfortable environment,this accounts for 60% of total heat loss.
  11. 18. Main mechanism for increasing heat during negative heat balance,involuntary muscle contraction that can increase body's heat production 5 times.
