Describe the physiological mechanisms humans have to prevent hyperthermia. Osmoregulation maintains the body's water and salt balance. Describe the essential role kidneys play in osmoregulation. The Kennicot Mine in Utah is the world's largest open pit copper mine. Mining has had a long history in the desert, though initial efforts were on a much smaller scale.
Dehydration can be simply an annoyance when mild but can be deadly when extreme.
Describe the course of increasing dehydration. Include both the physiological phenomena and the symptoms exhibited. While you may want to include how dehydration is related to hyperthermia, a complete description of heat syncope, heat stroke, and heat cramps is not necessary. Human survival in the desert can be enhanced by acclimatization. Describe how humans acclimate to the desert.
