Interesting Facts about the Human Heart Nov 16th 2013, 07:08 Your heart is probably the most important organ of your body; and why not? Considering its remarkable ability to keep the body going, and the various organs and organ systems functioning normally, it does deserve all the extra care and attention. But do you know all about this 'most important' part of your body? Here are some really cool facts about the heart that you probably didn't know- Size issues: The size of the heart can be estimated by looking at the fist-for kids, the heart is around the same size as one fist, and for adults it is two. It beats: In a day, the heart beats for more than 100,000 times; and in a whole lifetime, it can go as high as 2.5 billion beats. Pump it up: Your heart pumps out a lot of blood in the entire lifetime-by a lot, we mean approximately equal to 3 super tankers. Time factors: A normal kitchen faucet would need to be running for at least 45 years to flow out the same amount of water as the blood pumps out during an average lifetime. Electric it is! The heart has a power output ranging from 1-5 watts; calculated for 80 years, it equals around 2.5 gigajoules of power. Super cell: The human body contains over 75 trillion cells, and all of them have access to the blood pumped by the heart; except for the cornea of the eye. Lub dub: The heart contains 4 valves, and the lub dub sound of the heart beating is actually made by the closing and opening of the valves of the heart. Beats 4 you: The heart of a baby begins at around 4 weeks after conception. Tissue or liquid: As much as it looks like a reddish blue liquid, blood is actually a tissue, just like your skin, kidney and many other parts of the body. Speed it up: When you are at rest, it takes just six seconds for your blood to get from your heart to your lungs, and back; and about eight seconds for it to travel from the heart to the brain and back; and just sixteen seconds for it to travel from the heart to the toes and back to the heart. Men-women: A woman's heart beats much faster than a man's on an average- it beats for around 78 times a minute, while a man's heart beats around 70 times per minute.
