How The Heart Functions And Pumps Blood Through The Human Body?

We all know the heart is vital, and if it stops functioning (during cardiac arrest), your body begins systematically shutting down.

Let's glance at why the heart is essential to the whole body's Function.

The Heart Is The Generator Of Body

Consider your body as a computer. Your brain is both the processor and the hard drive. It's where everything is kept, all documents, memory and programs. But it also performs these activities, sending them through the rest of the system.


The heart, in any case, is the power supply. Also, without the power supply, nothing else works, and the system will not turn on. Your heart makes accurate electoral pulses that go through your body, providing energy to everything.

The thing is, assuming that power is switched off, everything doesn't simply close down; it begins to die. Your organs need a steady supply of blood and oxygen, and when the heart stops, both of these processes start. Presently, the body keeps a particular collection of oxygen stored up.

Blood, nonetheless, necessities to continue to move. That's why in cases of heart attacks and cardiac arrest, it's significant that you keep the heart pumping through chest compressions, then it is providing mouth to mouth.

How does It work?

The heart is composed of four chambers: the left and right atrium and the left and right ventricles. It's secured and anchored to the chest by a double-walled sac called the pericardium. 

Valves connect the heart's different chambers, and the rest of the body gets connected to the heart through valves.

Blood is circulated by the heart through the two pathways and the pulmonary circuit and the systemic circuit.

The pulmonary circuit runs deoxygenated blood through the right ventricle to the lungs. And here, it becomes oxygenized before getting back to the left atrium.

The oxygen-infused blood leaves through the left ventricle into the aorta in the systemic circuit. It enters the arteries and capillaries that supply your tissue with oxygen from that point.

At that point, the deoxygenated blood returns to the heart, and the procedure begins over again.

Like a muscle, the heart uses some oxygen, implying its arteries. When these arteries experience blockage, a heart attack can occur. It can also cause harm and terrifying to the heart. Inappropriate execution can also make an individual go into cardiac arrest.


Few people are born into the world with a heart that has not grown as expected in the womb before delivery - this is known as congenital heart disease.

Sometimes, you can acquire a heart condition from your family.

Cardiovascular System

Issues with your heart and circulation system include:

  • Angina
  • Stroke
  • Heart Attack

Heart disease can occur when your coronary arteries become restricted by progressive development of fatty material - called atheroma.

If your coronary arteries are blocked or restricted, it will weaken the blood supply to your heart. This is the most well-known type of heart disease, known as coronary heart disease (sometimes called ischaemic heart disease and coronary artery disease).

Your arteries might turn out to be so narrow they can't supply sufficient blood to your heart. This can cause angina - discomfort or pain in your chest, arm, neck, stomach or jaw.

If the fatty material ruptures or breaks off, a blood clot will develop, which can cause a heart attack (or stroke, if the artery affected carries blood to your brain).

Electrical System

Ordinarily, your heart will beat between 60 to 100 times per minute, and this regular rhythmic beating is subject to electrical signs being led all through your heart.

If the electrical signs inside your heart are interrupted, your heart can beat excessively fast (tachycardia), too leisurely (bradycardia) and additionally in an unpredictable manner. This is called an arrhythmia.

Conditions Influencing The Pumping Of your Heart

There are a few conditions that can harm your heart muscle, making it ineffective and incapable of pumping as proficiently as in the past:

  • Heart Attack
  • High Blood Pressure (hypertension)
  • Heart Valve Issues
  • Cardiomyopathy - this is a common term for illnesses of the heart muscle. In some cases, these infections are inherited from your family. And in some cases, they are caused by different things, such as viral contaminations.

There are also conditions - like high blood pressure (hypertension) - which mean your heart needs to work harder.

When your heart muscle can't satisfy your body's needs for blood and oxygen, you can develop different indications, similar to shortness of breath, ankle swelling and extreme tiredness. This is called heart failure because there is the failure to pump blood around the body and work effectively.


Your heart can't regularly work if the heart valves aren't working as expected, as it can influence blood flow through the heart.

Two main ways can impact the valves.

  • Valves can leak - this is called valve incompetence or valve regurgitation.
  • Valves can Stiffen and Narrow - This is called valve stenosis.

The heart is at the centre of your circulatory system, which is a grid of blood vessels that supplies blood to each part of your body. The heart stops beating; the body starts dying then please perform CPR. CPR (Cardiopulmonary resuscitation) is an emergency technique that can help save a person's life if their heart stops working. Seek medical assistance as soon as possible. Dial 88569-88569 and get a free Doctor Consultation.

If you are at risk, Don't wait! Call a doctor immediately. #BasEkCall at 88569-88569 with Medpho.
