Welcome to the Asian Heart Institute blog. It has taken us a while, over a decade, but now its time to broaden our outreach, and we hope to open every door that is available. Please follow us, and we promise to make it worth your while.
For our first post, a little trivia on your heart. Many people love to hear the little facts and figures that make for an understanding of the heart. So we thought we’d treat you to a little basic info, and we know you will be fascinated.
Your heart’s real address.
So where is your heart? OK, place your hand on your heart. Did you place your hand on the left side of your chest? Most people do, but the truth is that your heart is located almost in the center of the chest, right between your lungs. It isn’t ‘hanging straight’ like the pictures show but it is tipped slightly. A small part of it sticks out and taps softly as it beats against the left side of your chest, and that is why it seems as though it is located there. Watch your doctor place his stethoscope on your chest the next time you are visiting him and notice that he places it right in the middle.
How big is your heart?
The size of both your closed fists. Take a look: hold out your hand and make a fist. If you’re a kid, your heart is about the same size as your fist. If you are an adult, about the same size as two fists. It works harder as you grow up so its larger.
PHEW! THAT’S A LOT OF WORK!
Your heart beats about 100,000 times in one day.
About 35 million times in a year.
And during an average lifetime, your valiant heart will beat more than 2.5 billion times.
How strong is this little powerhouse?
Stronger than you realise. To pump blood, your heart uses the same amount of force as you would use to give a tennis ball a good squeeze. Even when you are being a couch potato and just sitting there, your heart muscles work hard. How hard? Twice as hard as your leg muscles when you are sprinting for the bus you are just going to miss!
The pulse of the moment.
You can feel your pulse by placing two fingers at the pulse points on your neck or wrists. That pulse you feel is blood stopping and starting as it moves through your arteries. As a kid, your resting pulse might range from 90 to 120 beats per minute. As an adult, your pulse rate slows to an average of 72 beats per minute.
Getting here, there and everywhere.
The aorta is the largest artery in the body. About an inch thick. The capillaries, on the other hand, are so small, that it takes ten of them to equal the thickness of a human hair.
12 milk bottles …..
You have about 5.6 liters of blood in you, which circulates through your entire body three times every minute. In one day, your blood travels … a total of 19,000 kilometers. That’s from Mumbai to San Francisco …. a non stop flight. Think YOU can travel that distance every day, for years and years and years?
The heart pumps about 1 million barrels of blood during an average lifetime. How much is that? Have you seen the big supertankers at sea? 1 million barrels would fill more than 3 super tankers.
lub-DUB, lub-DUB, lub-DUB.
Aha, the soundtrack of life. These “lub” and “DUB” sounds are made by the heart valves as they open and close. They’re famous, aren’t they, and when your heart works really hard, you can swear you can hear them. Well, you can.
