If you read the last post from us, you will know how important water is to our bodies. You will also know that approximately 70% of the human body is water. However, if you’re a curious person, you may wonder where all this water exists in our body.

Well, apart from being crucial to digestive, nervous, and other core processes in our body, the vast majority of it goes into our blood. It’s obvious, isn’t it? The most copious fluid in our body is our blood, so it makes sense for most of our body’s water to go into our circulatory system.

The engine behind our astounding circulatory system is, of course, our heart. It propels the blood at about 72 beats every 60 seconds. That’s more than a single beat every second! You may have known this but did you know that your heart is so powerful that it can squirt blood as far as 30 feet?

It shouldn’t come as a surprise to you that your heart is so powerful. After all, the muscles in your heart work the hardest of all muscles in your body. In every one of those 72 beats a minute, your heart pumps out 71 grams of blood to all parts of your body. In a single minute, this means that your heart sends out 5 litres of blood.

The muscles that your heart is made up of (cardiac muscles), however, are also known for sheer power. In the right circumstances, your heart has the capability to squirt blood as far as 30 feet.


What Is Needed for Your Heart to Squirt Blood to up to 30 Feet?

According to forensic experts whose job entails studying these interesting facts, in normal conditions your heart can squirt blood only up to six feet. But that doesn’t negate the heart’s capability in the right conditions.

What are these conditions? First and foremost, the heart needs to be beating at its maximum healthy rate. The number of beats the heart manages in a minute as mentioned above is applicable to a person at rest. The number of beats per minute will increase if the person is running, which is the first condition.

The second condition is the cut or opening through which the blood comes out. If the opening is small then the blood pressure will be maintained in the body, providing more impetus to the blood to spurt. These two conditions will result in the heart squirting blood to up to 30 feet.


Other Interesting Things about the Human Heart

While the above fact was a little morbid, there are many other amazing facts about your heart that you should know. For instance, did you know that your heart started beating when you were less than a month old? Furthermore, most people’s hearts are about as big as their hands clasped together. Finally, the beat that you hear in your chest is not really your heart beating. Instead, it is the sound of the opening and closing of valve leaflets in your heart!
