Which Chambers Are The Pumping Chambers Of The Heart?


In this post, I will answer the question: Which chambers are the pumping chambers of the heart? Knowing the answer would help you take care of your heart more appropriately.

I have previously discussed the 4 chambers of the heart in this post (kindly insert link to this topic), but we will delve deeper into the physiology and anatomy of the heart by discussing about which chambers are responsible in pumping blood.

The heart is the major organ of the circulatory system. It has two sides: the left and the right, and has four chambers: the left and right ventricle and the left and right atria.

The upper atria (2 chambers) receive blood from the body, while the two lower chambers - the ventricles discharges blood into the body.

The Heart has These Major Functions

1. Transport and Distribution of Oxygen and Primary Nutrients

It’s responsible in the transportation and distribution of oxygen and primary nutrients to all parts of the body for proper cell function.

Without oxygen and the required nutrients, the body cells won’t be able to function and perform their physiological processes. This can be fatal and could lead to death.

2. Helps in The Elimination of Waste Products

The heart can help eliminate waste products of metabolism by transporting them to the kidneys, stool or lungs to be excreted.

Which Chambers are The Pumping Chambers of The Heart?

The ventricles are the pumping chambers of the heart. They are also called the discharging chambers because they are responsible in discharging the blood back to the body.

On the other hand, the atria are the receiving chambers, which are responsible in receiving the blood from the body.

Why ventricles are the pumping chambers of the heart?

Because the ventricles are the pumping chambers of the heart, they have thicker, larger and more muscular walls than the atria.

The ventricles pump the oxygenated blood into the arteries, and then into the circulation of the different parts of the body.

The atria have thinner walls and are more inert because they only receive blood coming from the various veins in the body.

The blood from the veins that enters the atria is non-oxygenated blood or oxygen-poor blood, while the blood that is pumped by the ventricles to the arteries is oxygenated blood or oxygen-rich blood.

Tips in Checking If Your Heart is Pumping Normally

1. Consult Your Cardiologist ASAP, If You Notice any of These Symptoms

The normal heartbeat (heart rate) or pulse rate is 60 to 100 beats per minute. If your heart rate is higher or lower than the normal, consult your cardiologist.

  • Fast heart rate or tachycardia
  • Very slow heart rate or bradycardia
  • Heavy load on chest
  • Choking sensation
  • Discomfort or pain the chest
  • Fullness or indigestion
  • Pain in the arms, nape or shoulders

2. Have a Regular Cardiac Panel Tests

If you have increased rate of acquiring a heart ailment, request a cardiac panel test, such as CPK, AST, LDH, myoglobin, Troponin T and I, from your doctor or a clinical laboratory. You can do this every year or every six months.

3. Request a Stress Test from Your Doctor

A stress test will help determine your level of stress, so you can learn what physical activity to avoid and how to cope with physical exertion and exercise.

4. Take Your Pulse Rate (PR) Daily

You can monitor your PR or heart rate by placing your index and middle finger against an artery (wrist or neck), then counting the beats for 1 minute. You can detect that the blood vessel is an artery because it pulsates. Veins don’t pulsate.


Knowing the answer to the question: “Which chambers are the pumping chambers of the heart?” will help you know more about how your heart functions. This information will also help you realize the importance of maintaining a healthy heart.

Have you been aware of the pumping of your heart? Have you ever tried to take your pulse rate as your left ventricle pumps the blood? If you haven’t, try it now. It would be fun knowing how to take your PR, and knowing if your values are normal.
