Blood Circulation: Stages & Functions of Heart in Healthy Blood Circulation



A healthy heart is responsible for smooth blood circulation in the body. The blood circulation process comprises a series of functions of different heart parts. Blood circulation is the process by which the blood flows in all body parts through the blood vessels.

However, high blood pressure may lead to cardiovascular diseases. It may also hamper smooth blood circulation. Hence, you have to keep your heart healthy. You should go for regular checkups from the age of 18. Nearly 30% of Indian adults suffer from high blood pressure.

What is Blood Circulation?

The blood circulatory system is synonymous with the term cardiovascular system. The main function of the cardiovascular system is blood circulation. Blood circulation is the process by which the blood carries oxygen and other nutrients from the heart to other body parts. The heart receives oxygen when we inhale and releases carbon dioxide when we exhale. The heart thus helps in the process by pumping blood in a definite circle.

The blood acts as a medium of transportation in blood circulation. Parts of the heart that take part in blood circulation are:

  • Right atrium
  • Left atrium
  • Left ventricle
  • Right ventricle

Stages of Blood Circulation

Different parts of the heart mainly control the blood circulation process. The heart is as small as one’s fist. It is a complex organ. It conducts this circulation of blood in 4 different stages:

Pulmonary Circulation

In pulmonary circulation, the heart sends deoxygenated blood to the lungs. The blood picks up oxygen from the lungs. It circulates back to the heart.

Systematic Circulation

In systematic circulation, the heart then pumps this oxygenated blood throughout the body through blood capillaries. It then transfers oxygen. It collects all the impurities and carbon dioxide back to the heart through veins. 

The heart again sends this deoxygenated blood to the lungs to collect oxygen.

How Does a Healthy Heart Maintain Healthy Blood Circulation?

A healthy adult’s heart beats up to 100,000 times a day. It can pump 2000 gallons of blood daily to fill an average swimming pool. 

The functions of the Heart in blood circulation include:

Function on the Right Side:

  1. The deoxygenated blood is transferred through the inferior vena cava and superior vena cava to the heart's right atrium. 
  1. Then the tricuspid valve opens, and the blood moves from the right atrium to the right ventricle.
  1. The tricuspid valve closes, and the right ventricle squeezes to open the pulmonary valve.
  1. The blood flows through the pulmonary artery, taking all impurities to the lungs. It collects oxygen from the lungs.

Function on the Left Side:

  1. Deoxygenated blood now becomes oxygenated blood after it picks up oxygen from the lungs.
  1. It then comes to the left atrium through pulmonary veins from the lungs.
  1. From the left atrium, the oxygenated blood moves to the left ventricle via the mitral valve.
  1. The mitral valve closes, and the left ventricle opens the aortic valve.
  1. Finally, the oxygen-carrying blood travels from the aortic valve to the aorta and, thereby, to the whole body. 

Therefore, only a healthy heart can perform a series of functions for smooth blood circulation. If your heart is not healthy enough, you might face after-effects of it in the future. 

Signs of Poor Blood Circulation:

Poor blood circulation in the body is easily visible through organic eyes. You will notice certain changes in your body if you have poor blood circulation. The symptoms are:

  • Fatigue
  • Paleness in the skin
  • Numb different parts of the body
  • Dry skin
  • Brittle nails
  • Hair loss
  • Erectile dysfunction problem in male

How to Improve Blood Circulation?

A poor heart is solely responsible for poor blood circulation. In addition, obesity, diabetes and high blood pressure also contribute a fair share to poor blood circulation.

A Balanced Diet: Visit your dietician and get a balanced diet chart. Cut down on junk and fatty food. Include more plant-based items in your regular diet.

Regular Exercise: Exercise regularly to get rid of obesity and excess fat. Your body will release toxins through sweat.

Stay Hydrated: It is very important to keep your body hydrated enough for smooth circulation. But do not overdrink water.

Take a Bath Regularly: It is important to remain hydrated. But it is equally important to take a shower regularly.

Control your Blood Pressure: Your heart plays an important role in blood circulation. So caring for the heart is important. Keep your blood pressure within the normal range (120/80 mm Hg).

Good Night’s Sleep: Your body needs rest to function properly. Hence, sleep for at least 6 hours if possible. Proper resting is essential for a body to function properly. If there is a lack of sleep, your body might act unusually.


A common person can’t know everything about health. Your blood circulation depends on the condition of your heart. But you can keep yourself fit and healthy through your healthy lifestyle. After a certain age, you have to seek medication as your body fails to perform certain functions smoothly with the advancing age.
