Answer:
1. The physiological changes that will occur when someone lives at altitude for an extended period include increased production of more red blood cells.
2. The changes are advantageous as the person can survive lower altitude better and strenuous activities that interferes with breathing.
3. The specific physiological pathway that results in the changes described involves decrease in pulmonary ventilation at high altitude leading to hypoxia then hypoxemia. The body then produces more red blood cells to counteract the lower oxygen saturation in blood in high altitudes.
