Science Story: Surprising facts about the human heart

Before humans knew anything about biology we knew the heart was essential to the human experience. Here are six facts about this amazing organ.

#1 The average heart beats millions of times per year, 115,000 times per day and 80 times per minute!

#2 The human heart creates so much energy in a day that you could use it to power a car for 20 miles.

#3 We are born with a fixed number of heart cells.

A baby heart will contain the same number of cells as an adult heart. But they’ll be less than one-fifteenth the size.

#4 The iconic heartbeat sound is actually caused by the four valves of our heart opening and closing as it filters and distributes blood.

#5 For Ancient Egyptians the heart was considered to be the key to the afterlife.

They also thought that the heart as well as other major organs could move about independently in the body.

#6 A woman’s heart is 25% smaller than a man’s and it pumps about 10% less blood in a heartbeat as a result.

This causes the average heart rate for women to be higher than that of a man by 8-10 beats.

Good information. Sadly, I just lost my sister to heart failure. Throughout her illness her fiance' and I both learned so much thanks to her nurses and doctors about a woman's heart. Take care of your heart!!!

Mike Gilmore, I think that the blood gets filtered through the liver. I'm no doctor or scientist but I have seen some medical shows and think this information is pretty near the truth.

Only thing I did not know was that we are born with a fixed number of heart cells.

Mike Gilmore

Just a topical comment Does the heart beat of a man or woman change and does the size increase or decrease should they have a sex change?

james parrillo, old wives tale! I said years ago! Way before there were scans and etc., Like they have now! Beside, it was a joke! Thank you, Helga, widow of Jim!

Even a minute heart muscle separated will start beating.

tbear, I never heard of this method of determining the sex of the preborn child. I wonder why scans are so necessary, if the doctors can tell so much without them. Thank you, Christine, James's wife

#6 Is the reason, years ago, they said when you were pregnant and they counted the baby's heartbeat, they could tell if it was a boy or a girl! They were right 50% of the time! 👍😊
