Most individuals respond to a prolonged stay at high altitude by producing more hemoglobin, producing more red blood cells, or both.

Question

Quizplus · Accepted Answer

This is true. The body's response to prolonged high altitude exposure is to increase the production of hemoglobin, the protein in red blood cells that carries oxygen, and also to produce more red blood cells to transport oxygen more efficiently to the body's tissues. This is called acclimatization and helps the body compensate for the lower oxygen levels at high altitude.
