Here are 11 important facts you didn’t know about human heart.
- 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 heartbeat 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.
