What you need to know about heart chambers

The more you learn about the heart chambers, the closer you are to learning about the heart itself, one of our vital organs.

Hearts beat roughly 100,000 times per day and push almost 5,000 gallons of vital blood through the human body within this time as well.

It eliminates waste and brings nutrient and oxygen-rich blood to our organs and tissues.

Needless to say, the heart is an extremely hard-working muscular organ.

Due to its hard-working abilities, it consists of many different parts which help it function efficiently.

In this article, we’ll delve into everything you need to know about the heart chambers — our heart’s essential tools for doing what it does best: keeping us alive.

Understanding the Basic Anatomy of the Heart


The heart is around the size of a small baseball, located just to the left of the center of our chest.

As we all know, the heart contracts. And when it does, it pumps blood throughout the body, distributing deoxygenated blood to the lungs where the blood is then filled with oxygen and releases carbon dioxide.

The heart, its blood vessels, and the blood within these vessels are known as the circulatory system.

The average person contains about 8 pints of blood within this system which is continually pumped all throughout the body.

The heart itself contains four chambers in two distinct areas:

  • Ventricles: two lower chambers which discharge blood
  • Atria: two upper chambers which receive blood.
  • The chambers are therefore responsible for the main blood distribution for the oxygenization process.

In terms of the heart’s wall, it contains three different tissue layers:

  • Myocardium: the heart’s muscles
  • Epicardium: a protective layer consisting mainly of connective tissues
  • Endocardium: protective lines within the heart for the chambers and valves

While this only scratches the surface in terms of the anatomy of the heart, in this article, we’re focusing only on the heart chambers and therefore will only be outlining the parts of the heart that focus on these

Looking Deeper: Heart Valves and Chambers


The heart also contains four different valves which help keep blood flowing in the same direction.

Therefore, as humans, we’re quite thankful for these valves.

These heart valves are as follows:

  • Mitral valve: this valve is located between the left ventricle and the left atrium.
  • Aortic valve: this valve is found between the aorta and the left ventricle.
  • Tricuspid valve: this valve is located between the right ventricle and the right atrium.
  • Pulmonary valve: this valve can be found between the pulmonary artery and the right ventricle.

The best way to describe the sound of a heartbeat through words is by the classic, “lub-DUB”.

Here’s what happens when you hear those two sounds:

The “lub” part of the beat is created by the mitral and tricuspid valves closing, while the “DUB” sound of the beat is created by the aortic and pulmonary valves closing.

A normal human heart has two lower and two upper chambers, and as mentioned earlier, are responsible for the oxygenating process. This is how:

The right atrium takes the deoxygenated blood from the body and pumps it into the right ventricle, then the right ventricle pumps the deoxygenated blood back into the lungs where it’s filled with oxygen again.

The left atrium then takes the oxygenated blood from the lungs and passes it over to the left ventricle, where it distributes the blood throughout the rest of the body.

As we said, the heart is a pretty impressive muscle organ.

Medical Issues with Heart Chambers


Through all that hard work, sometimes the heart chambers can develop issues, as with all parts of our body.

When an individual experiences a problem with their heart chambers, the issues tend to fall into the following disorders. We will outline the issues in the category of arrhythmias, or improper heart beating, as this function is the chambers’ main responsibility.

While some of these issues may seem a bit nerve-racking (or should we say chamber-racking), there are treatments for nearly all of them.

Atrial Fibrillation (Afib)

Over 2 million U.S. citizens suffer from atrial fibrillation. With this disorder, the heartbeat becomes irregular and fast-paced due to disorganized signals being sent from the heart’s main electrical system.

While this disorder isn’t life-threatening, it can become the cause of alternative rhythm issues, heart failure, strokes or constant fatigue.

In fact, people with Afib are 5 times more likely to suffer from a stroke than those without.

Atrial Flutter (AFL) 

This disorder is similar to Afib as it also causes fast beating found in the atria area. AFL, however, is caused by an electrical wave which circulates quickly around the atrium. It will circulate around 300 times per minute. This disorder can also increase the chances of having a stroke.

Sick Sinus Syndrome (SSS)

This is actually a group of symptoms which act as a sign that our heart’s electrical pacemaker, also known as the sinus node, is malfunctioning.

With SSS, the heart rate can become either fast or slow. Treatment includes having a pacemaker surgically implanted.

Sinus tachycardia is a harmless increase in a person’s heart rate which occurs when the individual develops a fever, becomes excited, or if he/she exercises intensively.

When this happens, treatment isn’t required unless the event is caused by an underlying issues such as hyperthyroidism, anemia, or very rarely, Tachycardia.

Ventricular Tachycardia (VT)

VENTRICULAR TACHYCARDIA (VT)

This is a serious form of arrhythmia and is found with other major heart diseases, however, can also occur in individuals with normal hearts.

VT can form into a disorganized and dangerously fast heartbeat known as ventricular fibrillation which requires extensive treatments.

These treatments may include radiofrequency ablation or surgery. Patients with this disorder are often equipped with an implanted defibrillator. 

How to Keep Your Heart Chambers Healthy


Now that you’ve learned the dark side of the heart and its incredible chambers, it’s time to look at our chambers in a more positive and optimistic light.

To avoid suffering from any of the disorders as mentioned above, we suggest making some tweaks to your lifestyle.

These recommended life adjustments (or upgrades) include the following:

Eat Real Food

vegetables and meat

Fast food isn’t real food.

Start making your meals at home, keep your cholesterol low and make every plate as colorful as the rainbow.

According to experts, people who have high cholesterol levels have a narrower aortic valve which can lead to heart issues.

One of the main culprits for high cholesterol is processed foods.

Steer away from these foods and begin reading labels on canned food. Create a new diet plan that consists of non-processed nuts, vegetables, veggies, grains, and beans.

Your heart will love you for it.

Move That Body!

Okay, sure. Enough with everyone telling you that you need to exercise.

But hear us out:

By moving only a bit more each day, you’ll be able to develop habits that are proven to help you live longer, healthier, and happier.

Try doing something that you enjoy.

It doesn’t have to be the loathes spinning class or jogging. Take up swimming or go for walks in the park. Play tennis a couple times a week or throw a Frisbee around with your beloved fur baby.

Whatever you can do to get you off the couch, do it.

Practice Mindfulness

PRACTICE MINDFULNESS

You’ve probably seen this suggestion come up in a lot of subjects these days.

But there’s a reason for it.

Focusing on the present moment for short periods throughout your day can help your heart significantly.

In fact, individuals who score the highest levels of mindfulness also had much better heart health compared to those who weren’t as mindful.

By putting a bit of time aside to focus on your breath and your surroundings, you’ll also be able to develop a healthier BMI, and a faster glucose level.

Heart Chambers: Final Thoughts


Our heart chambers are incredible.

They are key players in replenishing the blood that feeds our body and keeps us ticking properly.

Yes, there’s a list of possible issues that can arise in these important heart chambers.

However, there’s also a hefty list of lifestyle changes you can incorporate to ensure your heart, so your entire body stays healthy and continues to thrive for many years to come.
