An Overview of the Human Heart

What the human heart is and how it functions.

The human heart has been associated with love, courage and power for thousands of years. But what exactly is the human heart and what exactly does it do?

I'm Heart Healthy Henry and I have the answers you've been looking for when it comes to the functioning of the human heart.

What It Is

The heart is a hollow muscle that pumps blood through the body's blood vessels. It does this by contracting and expending, causing the blood to move through the heart into and through the vessels. The average heart beats seventy to eighty times per minute.

What It Looks Like

Visions of a pretty, glowing red, heart shape pulsing in our chests may look great on cartoons, but it's nothing close to reality. In fact, the human heart looks more like an upside-down pear than it does the hearts we were all drawing in grammar school.

There are four chambers in the human heart -- two atria and two ventricles. Each half of the heart has one atria and one ventricle and a wall called the septum divides the two halves of the heart.

Good Things Come in Small Packages

Even though the human heart is one of the most important parts of our bodies, it's relatively small. In fact, it's only about as big as a clenched fist and it weighs in at a surprisingly light average of 11 ounces.

What It Does

We've already mentioned that the human heart pumps blood throughout the body, but let's look a little more closely at how the heart works.

When the human heart is pumping blood throughout our bodies, it's also making sure that all parts of our bodies are getting the materials our bodies need in order to function properly. The brain needs oxygen and our hearts bring that oxygen to our brains. Muscles need oxygen too and our hearts also make sure that our muscles get enough.

Without our hearts, the different parts of our bodies would not be able to get enough of what they need in order to do their jobs.

Keeping Our Hearts Healthy

Because our bodies do rely on our hearts so much, it's important that we do everything we can in order to keep our hearts healthy. Taking dietary supplement such as the one at this website as well as eating properly and getting proper exercise will ensure that your heart is working at its best.

While the human heart is a relatively small part of our bodies, it certainly plays a big role in our lives and in our health.
