00:00Your heart is about the size of your fist, but it works like a powerful pump.
00:04It beats around 100,000 times a day, pushing blood through your body.
00:09This blood carries oxygen and nutrients to your organs, muscles, and brain.
00:15Even while you are resting, your heart never stops working.
00:19Every heartbeat is a small reminder that your body is alive and active.
