what is heartbeat and pulserate
Answers
Answer:
Explanation:
Every heartbeat results in blood moving forward through your arteries. You can feel this movement as a 'pulse' by placing two fingers over the artery of your wrist. Your pulse rate tells you how fast your heart is beating.
Your pulse is your heart rate, or the number of times your heart beats in one minute. Pulse rates vary from person to person. Your pulse is lower when you are at rest and increases when you exercise (more oxygen-rich blood is needed by the body when you exercise). Knowing how to take your pulse can help you evaluate your exercise program.
A heartbeat is a two-part pumping action that takes about a second. As blood collects in the upper chambers (the right and left atria), the heart's natural pacemaker (the SA node) sends out an electrical signal that causes the atria to contract.
