Question

1. Our breathing rate is much higher when running than when walking. Explain the advantage of this to the body.

Answer 1

As muscles move more – for example, if we go from walking to running – the heart pumps faster (increased heart rate) to increase the blood supply and we breathe more quickly (increased respiratory rate) to get more oxygen into the blood.

Answer 2

Answer:

There is more requirement of oxygen while we are running. Thus breathing rate increases to allow more oxygen into the body. This helps the body to keep running and avoid muscle cramps
