1. Reationship betweeen heart beat and pulse rate
2. Artery walls are very strong and elastic . why?

Dear student,

1. The pulse rate is equal to the heartbeat,
​​​​​​This is because the contractions of the heart cause the increase in blood pressure in the arteries this can be felt as the pulse. So the measurement of the pulse is a direct measure of heart rate.

Normal heart rate or pulse rate at rest:

  • Children (ages 6 - 15) 70 – 100 beats per minute
  • Adults (age 18 and over) 60 – 100 beats per minute
2. The heart pumps blood directly into the arteries and hence there is a lot of pressure in the arteries. Hence the wall of the arteries are strong and elastic to prevent damage due to high pressure.

Regards
