Explain the Term
Pulse rate
उत्तर
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.
