All About the Human Heart

1. According to research, if you make a fist with your hand, it should be an indication of how big your heart is. Generally, it’s slightly larger than your fist, unless there are underlying conditions. But, the general rule of thumb is that an adult-sized and healthy human heart should weigh between 8 and 12 ounces. 

2. You’d be surprised to find that your heart is mainly made up of strong muscles. This same muscle is responsible for the action of pumping blood to and from your heart. To successfully do this, blood is pumped by your heart muscles when they relax and squeeze it. This creates a regular rhythm that your heart maintains as long as you’re healthy. This rhythm that you can listen to from your chest is what’s called a heartbeat. 

The order you get, the slower the pace of your heartbeat. The average speed of your heartbeat should be around 70 beats per minute. This allows for more than 4 quarts of your blood to pass through your heart at every minute. 

3. It’s important to know that your heart is divided into two halves. But that’s not where it ends. Each half is also divided into these two hollow sections. These are then called chambers. The chambers are often called atrium as a collective, but they each have a name to distinguish them. The upper chamber is known as the atria, while the lower one is known as a ventricle. 

Your blood from the rest of your body will flow into the right half. The most important thing to note about this type of blood is that it contains carbon dioxide, which is a waste product. It’s important for this blood to pass into the right ventricle. This is where blood is pumped into the lungs. As a result, oxygen plays a crucial role in helping you release the carbon dioxide. 

4. If you have any problems with your heart, and you’re not sure how to identify them, you’re not alone. It’s also important for you to teach your kids how they can know if something is wrong with their hearts. The most common way to discover a problem is to look for an irregular heartbeat. Other things that you can assess are what happens to your heart after you eat or exercise.
