<h3><u>Answer:</u></h3>

<u>(a) Reason for the heart beating fast:</u>

  • When we exercise/run the muscles work hard and need more oxygen.
  • So, when Ravi's heart beats faster more blood can be pumped to the muscles thus giving the oxygen required.

<u>(b) Organs involved along with the heart to help Ravi complete his race:</u>

  • The main organs involved along with the heart are quadriceps, hip flexors, hamstring, glutes and calf muscles.
  • The nervous system, muscular system, skeletal system, respiratory system and circulatory system function effectively when a person runs.
