Question

Why does breathing rate increase at high altitudes?

There is an increased concentration of oxygen in the air, which speeds up the respiratory process.

The lower air pressure at high altitudes causes an increase in oxygen absorption.

The reduced oxygen availability at high altitudes triggers the body to increase breathing rate to obtain more oxygen.

The high altitude causes an increase in carbon dioxide production, which forces the body to exhale more frequently.
