Explain the term Pulse rate. |
|
Answer» Pulse rate indicates the rate at which the heart beats. Each heartbeat results from the contraction (systole) and relaxation (diastole) of the heart. Both the auricles contract at a time and pour the blood into the main artery (dorsal aorta). The systole and diastole take 0.8 secs., which is 75 beats per minute. |
