Your heart is the most important muscle in your body
It 's the size of the first, but your heart is the powerhouse of the cardiovascular system. You can pump more than a gallon of blood around your body every minute, 60 minutes per hour, 24 hours a day. What is round trip of over 1,400!
Journey through the arteries, the blood carries oxygen and nutrients essential to the ends of your body. After returning to the heart through veins, blood is pumped to the lungs, where carbon dioxide and other waste gases are removed and oxygen is supplied.
All the while, your heart is doing the work. This process goes on when you're awake and when you are asleep. And you could not live without it.
