Question

Why does the rate of breathing increases while walking uphill at the normal pace in the mountain?give two reasons

Answer 1

1. the rate of breathing increases because higher we go lesser the oxygen we get, so as our breathing rate increases our body tries to intake more oxygen to fulfill the demand of oxygen in our body.
2. we walk against gravity as we climb uphill hence our body requires more energy and energy in our body is supplied by breaking down of oxygen molecules hence, to supply  more oxygen to our body our breathing rate increases.

Answer 2

As we afford More amount of energy to climb up against the gravity the energy decreases & so we breath too much to regain the energy and oxygen
