The human heart is an amazing organ- fact ! I have found a list of 10 heart facts which demonstrate how hard working and amazing the heart is.

1) Despite weighing less than a pound coin, the heart is the size of two adult fists. Very tiny considering the amount of work it is expected to do.

2) The human body contains 5.6 litres of blood which the heart distributes a massive 2000 miles daily, thats 60 000 miles a month. I dont think you could drive that amount of miles per month.

3) Heart has its own distinct rhythm made up of two sounds lub and dub, which occur due to heart value opening and closing as blood passes through the atria and ventricles.

4) Women have faster heart rates than men

5) Have you ever wondered how many heartbeats you have per day, well does 100 000 sound about right!That makes around 35 million times a year.  Is it any wonder we skip some!

6) Adults should have a pulse of 70 heart beats per minute, but if you are child your heart works much faster and beats sometimes up to 120 times a minute.

7) The heart muscle is the hardest working muscle in the body even while it is not pumping blood, as it works harder than an athletes leg muscles during the 100 metre sprint.

Last but not least the most common time to have a heart attack (myocardial infarction) is between the morning hours of 8 and 9.
