Question

What is the average number of heartbeats per minute of an adult person while resting? Explain why, the heart beats faster during and after an exercise.

Answer 1

Explanation:

72 beats per minute while resting,

while exercising and after it remains fast, as our body requires more oxygen, so as blood transports oxygen to every single cell of body, so as you know heart's function is to remove deoxygenated and release oxygenated blood , so as we do exercise the oxygen of our muscles get used up, so to give them more oxygen in a faster way, so muscle fatigue doesn't occur, heart beats fast and makes the flow of blood or blood pressure faster
