The heart beats on an average of 72 times per minute; 100,000 times per day; 3,600,000 times per year; and 2.5 billion times in a lifetime.The heart produces power output ranging from 1 to 5 watts.
After conception, the first heart – a tiny group of Cells starts to beat at four weeks of pregnancy.
The beating sound is the clap of valve leaflets opening and closing.
As heart has its own electrical impulse, it can keep on beating even after separation from the human body, but there must be sufficient oxygen supply.
The heart pumps blood via its arterial system to almost all of the body’s Seventy-five trillion cells. But, there is no blood supply for corneas.
The Human Heart pumps around 1.5 million barrels of blood during an average lifetime which is enough to fill about 200 train tank cars.
For adults, the size of the heart is about the same size as two fists.
For children, the size of the heart is about the same size as their own fist.
Blood takes only six seconds to go from the heart to the lungs and back, only eight seconds to go to the brain and back, sixteen seconds to reach toes and travel all the way back to the heart. This all happens while the body is at rest.
Studies show an interesting link between education and heart diseases. More education = less heart disease.
