Happy Valentine’s Day! Here’s a Heart!

This is how I feel about Valentine’s Day this year. It’s all about the real heart. What is this symbol of love and emotion anyway? It’s a muscle so strong that it doesn’t stop beating – ever. The average heart beats over 2  1/2 billion times in a lifetime, and it only weighs about 11 ounces.

Your healthy heart pumps 2,000 gallons of blood through 60,000 miles of blood vessels each and every day! Want a real-life example? A kitchen faucet would need to be turned on full force for at least 45 years to equal the amount of blood pumped by the heart in an average lifetime. Grab a tennis ball and squeeze it tightly: that’s how hard the beating heart works to pump blood.

heartBecause the heart has its own electrical impulse, it can continue to beat  even when separated from the body, as long as it has an adequate supply of    oxygen. Ever wonder where the thump-thump sound comes from when your heart beats? It’s the sound of the four valves closing! Cool, huh?

Our society has accepted that cocaine is “everywhere.” This drug is more dangerous to your heart than you may think. Cocaine affects the heart’s electrical activity and causes spasms of the arteries which can lead to a heart attack or stroke, even in healthy people.

 

So, if you wondered just what that fairly small muscle really does – now ya know!  Happy Valentine’s Day!
