Homeostasis

• Homeostasis "to stand" lit. "to stand equally"; is the property of either an open system or a closed system, especially a living organism, that regulates its internal environment so as to maintain a stable, constant condition. Multiple dynamic equilibrium adjustment and regulation mechanisms make homeostasis possible.

High Altitude• are regions on the Earth's surface (or

in its atmosphere) that are high above the sea level

Human Limits• 29,000 feet without needing oxygen• bodies were not created to handle

the incredibly frigid temperatures• the high winds, or the lack of oxygen

that are common in places such as these

• we are forced to come properly prepared mentally and physically.

Adaptations• breathing response intact• blood response, intact so that the

blood can carry more oxygen• tissues have to be able to utilize the

low oxygen• mitochondria, the small capillaries in

the muscle beds, have to be augmented

special equipment and clothing in extreme climates

• Many warm layers: pants, hiking boots, pile jacket, down jacket, light hat, light gloves. wind pants, double boots, wool hat, gloves

• Special equipment: Glacier glasses, harness, gators, heavy gloves, face mask, oxygen bottle, mask and regulator, radio.
