Question

 What change occurs in heart beats if a person runs for a while? Why?

Solution


(b) A person's heart beats faster after running for a while. This is because his body needs more energy after running.

When the heart beats faster, it pumps the oxygenated blood more rapidly to the body organs, thereby providing more oxygen to our cells (for rapid respiration) to produce more energy.

  Is there an error in this question or solution?
