Question

conducts the activity to observe the pulse rate and heart beat rate​

Answer 1

Answer:

Pulse/heart rate is the wave of blood in the artery created by contraction of the left Ventricle during a cardiac cycle. The strength or amplitude of the pulse reflects the amount of blood ejected with myocardial contraction (stroke volume). Normal pulse rate range for an adult is between 60-100 beats per minute. A well-trained athlete may have a resting heart rate of 40 to 60 beats per minute, according to the American Heart Association (AHA).[1]
