Extremely high altitude: 18,000+ feet (5,500+ metersHeights from 5,000 to 8,000 feet are considered moderate; high altitude extends from 8,000 to 14,000 feet, very high altitudes from 14,000 to 18,000 feet, and extreme altitude beyond that.

Answer 2

Answer:

The effects of high altitude on humans are considerable. The oxygen saturation of hemoglobin determines the content of oxygen in blood. After the human body reaches around 2,100 metres above sea level, the saturation of oxyhemoglobin begins to decrease rapidly.
