Why the rate of breathing increases by 20 to 30 times during vigorous exercise? |
|
Answer» Breathing rate increases because during vigrous exercise we require a large amount of energy as compaired to before so for this energy we requires a large amount of oxygen which helps in producing energy at higher rate and quickly so our breathing rate increases and we get a required amount of oxygen When we exercise, our breathing rate increases to compensate for the increased need of oxygen that is required for our body to release energy. And we breathe harder and faster because: respiratory muscles are stimulated by sympathetic nerves in order to increase the rate of breathing Saheeda nu naman Jai hind.?? |
