Your heart works hard for T 34 you every minute of every day. Help it function at its best hink you have a busy day? Consider the day your heart is having. While responding to your moment-by-moment demands, it continuously pumps oxygen and nutrientinfused blood to every one of your 75 trillion cells. But its job has just begun. Exchanging oxygen and nutrients for waste products, it pumps the blood back through miles of vessels. Finally, it sends the waste to the lungs for exhalation—all in less than a minute.
