How Much Blood Does The Heart Pump In One Day?

An average human heart beats at 72 beats per minute which adds up to an approximate value of 2.5 billion times during an average lifespan of 66 years. It weighs around 250-300g in females and 300-350g in males. It has four chambers, the Right Atrium, Right Ventricle, Left Atrium and Left Ventricle.

The Atria are the receiving chambers while the ventricles are the discharging channels. The blood flows inside the heart in one direction. Also read on how does the heart pump blood. This article also explains about the other conditions like enlarged heart problems and blood clots in heart.

Blood Pumping Procedure

  • The deoxygenated blood is collected from all parts of the body by the right atrium.
  • This deoxygenated blood is pushed into the lungs by the right ventricle.
  • This takes place by the Pulmonary Artery.
  • The oxygenated blood is collected from the lungs by the left atrium.
  • The oxygenated blood is pumped to all body parts by the left ventricle.
  • This is carried out by the Aorta.
  • The filling up and emptying of the left side and the right side occurs in unison.
  • The same amount of blood is pumped by each chamber.
  • The left ventricular wall is three times thicker than the right ventricle.
  • More cardiac muscle is needed by the left ventricle to give a stronger push to the blood.
  • So the blood pressure is highest in the left ventricle.

How Much Blood Does The Heart Pump In One Day?

  • An average heart pumps about 2.4 ounces (70 milliliters) of blood per beat of heart.
  • If 72 beats occur per minute, then about 1.3 gallons (5 Liters) of blood is pumped per minute.
  • About 1,900 gallons (7,200 Liters) of blood is pumped per day.
  • This adds up to almost 700,000 gallons (2,628,000 Liters) of blood per year and about 48 million gallons (184,086,000 liters) by a life span of 70 years.

How Does the Heart Pump Blood?

The heart is located between the lungs behind the breast bone. About two-third of the heart lies to the left side of our midline of the body and about one-third to the right side. It appears as a cone-shaped and hollow muscle mass. The heart is a double pump made up of cardiac muscles. It pumps the blood throughout our body by repeated rhythmic contractions and relaxations. The term ‘cardiac’ is derived from a Greek word, ‘Kardia’ meaning ‘related to heart’.

The Action of the Heart

  • The blood enters the atria to fill it, called the Arterial Diastole.
  • The sino-atrial node is present in the right atrium.
  • It generates a nerve impulse. This cause the contraction of the atria called the Atrial Systole.
  • The heart rate increases due to the sympathetic nerve impulses and decreases by the vagus nerve impulses.
  • The blood pressure in the atria is more than in the ventricles.
  • The AV Valve opens and the blood is forced into the ventricles.
  • The impulse then reaches the atrio-ventricular node.
  • A delayed impulse of about 0.2 seconds helps in filling the ventricles, called the Ventricular Diastole.
  • Now the impulse enters the ventricles and moves through the bundle of his present in the septum.
  • Contraction of the ventricles occur which forces the blood out of the aorta and pulmonary artery. This is named as ventricular systole.
  • The AV valves closes to prevent the blood from returning back to the atria.
  • The semi-lunar valves are opened forcefully due to higher blood pressure in the ventricles.
  • When the elastic artery walls expand, it is called a Pulse.
  • The arteries recoil and squeezes the blood away from the heart due to fall in the pressure.
  • The fall in the ventricular blood pressure results in the closing the semilunar valves.
  • So the blood is prevented from flowing back into the ventricles from the arteries.

Enlarged Heart Problems

Cardiomegaly is the medical term used for the problem of enlarged heart and it is not considered as a disease. This can be a symptom of any other severe health complication due to which a person can suffer from enlarged heart problems as well.

This cannot be prevented, but can be treated with the help of a few treatment options. Cardiomyopathy is a disease that occurs in the heart muscles and is responsible for causing this condition. People suffering from cardiomegaly may also suffer from cardiomyopathy. Read on to know more about this condition.

Symptoms of Cardiomegaly

People suffering from this condition may not experience any kind of symptoms most of the time. In severe cases, one may experience the following symptoms.

  • Coughing
  • Swelling, which is edema
  • Irregular heart beat which is arrhythmia
  • Dizziness
  • Breathing trouble

Causes of Cardiomegaly

  • The enlarged heart problems can be detected with the help of x-rays to find the causes of this condition.
  • Short-term cardiomegaly can be caused due to the stress caused on the body during rhythm or heart valve abnormalities, other medical conditions and pregnancy.
  • Cardiomyopathy is a major reason for causing this condition and this can further result in weakening of the heart muscles.
  • Overabundance of iron, thyroid disorders, abnormal heart beat, congenital heart defect, heart valve diseases and high blood pressure are a few other causes of this condition.


Correcting the underlying cause can help in treating the condition of enlarged heart. Certain potential remedies such as medical surgery, procedures and medications can help in treating this condition. Heart transplant can also be opted if all the treatment options fail.


  • A person suffering from enlarged heart problems can suffer from formation of blood clots in and around the lining of the heart.
  • This condition can lead to strokes or heart attacks if left untreated.
  • The rhythm of heart beat can get disturbed due to this condition further leading to fainting.
  • This condition can sometimes lead to extreme cases such as heart attacks or even death.

The following article explains about causes, symptoms and treatment required for blood clots in heart.

Blood Clots in Heart

Blood clotting is a natural phenomenon that occurs during an injury in order to stop the flow of blood. However, excess formation of clots can be a symptom of an underlying disease or it can also lead to a severe health complications.

Blood clots in heart should be treated immediately as there are chances for this condition to lead to the death of a person as well. This can lead to heart attacks and strokes due to the poor supply of oxygen and blood to the heart. Read on to know about the causes, symptoms and treatment of this condition.


  • The condition of blood clots in heart can occur when the inner blood vessel walls also known as endothelium get damaged.
  • Rheumatoid arthritis and pregnancy can also result in the formation of clots in the heart.
  • People who have undergone a surgery are more prone to suffer from this condition.
  • Certain lifestyle habits like consumption of excessive alcohol, smoking can lead to the formation of clots.
  • Obesity is another major reason as the fat content formed in the blood vessels may block the flow of blood through them further resulting in blood clots.
  • This condition is also seen in women who use contraceptive pills.
  • Lack of physical activity is another major reason that results in causing blood clots.


The symptoms of this condition may vary from person to person. A person suffering from blood clots in heart may experience feeling of discomfort and shortness of breath. Chest pain is one prominent symptom of this condition.

This condition can also affect the oxygen supply to the heart muscles which can result in heart attacks. Fainting, dizziness and high blood pressure are a few other symptoms of this condition. In extreme cases, a person may also experience coughing up blood.


  • The condition of blood clots in heart can be treated with the help of oral medication and through a surgery as well.
  • Thrombolytic medication is the best treatment that can be used to overcome this condition.
  • Anti coagulant medications can also be used to remove the blood clots and anti platelet drugs like heparin can also be used to dissolve the blood clots.
  • These can also be removed surgically with the help of catheters to open up the blocked blood vessels.
