Why does the rate of breathing increase while walking uphill at a normal pace in the mountains? Give two reasons.
The rate of breathing increases while walking uphill at a normal pace in the mountains.
1. It is because as we go up the hill above sea level the concentration of oxygen is greatly reduced. So we have to breathe more to get required amount of oxygen.
2. While walking uphill a lot of oxygen is used by our body to release energy from glucose.
3. This leads to lack of oxygen in the cells.
4. We take in oxygen when we breathe.
5. Hence to increase the amount of oxygen intake there is an increase in breathing rate during walking uphill.
