Understanding The Importance Of Blood Circulation

Photo of author

The circulatory system of the body is also known as the cardiovascular system or vascular system. It enables the transportation of oxygenated blood to the tissues and other organs of the human body. The circulatory system plays an important part in the functioning of the human body. The heart pumps blood through the cardiovascular network to the vital organs of the human body and provides them adequate nutrients and oxygen. It also transports the waste products and harmful chemicals away from them. Blood circulation is done by the vascular system in such a way that the oxygenated blood is transported from the heart to the entire body. It can further be categorized into pulmonary, systemic and coronary circulation.

1. Pulmonary Circulation

The pulmonary circulation involves the transfer of blood to and from the heart and lungs. The deoxygenated blood is carried away from the right ventricle of the heart to the lungs and returns oxygenated blood into the left atrium via the pulmonary vein.

2. Systemic Circulation

The systemic circulation involves the functional blood supply to the tissues of the entire body and it carries oxygen and adequate nutrients to the cells of the body. Also, the waste is taken away through the lungs and are expelled.

3. Coronary Circulation

Coronary circulation involves the supply of blood to the heart through the coronary arteries. The two coronary arteries originate from the aorta and an increased aortic pressure supplies the blood to the heart.

Diseases associated with poor blood supply

Proper blood flow throughout the body is important as the poor blood supply is linked with many health problems. In Fact, the good blood supply is vital for the functioning of the organs of the body as they are highly dependent on it. Some of the diseases that are very much associated with the blood supply include

1. Atherosclerosis

Atherosclerosis is a condition in which the walls of the arteries thicken due to the buildup of fatty acids. These fatty acids are known as plaque and it makes the arteries narrower and leads to reduced or blocked blood flow. Atherosclerosis is also known as hardening or blockage of arteries. This condition can cause a number of serious health problems and it depends on the condition of blockage and the arteries of the brain, heart, kidney, and legs are most affected. The partial blockage of the arteries of the heart due to atherosclerosis can lead to chest pain and when the heart muscles die due to complete blockage, it leads to a heart attack. Also, the risk of the stroke increases with the poor blood circulation in the areas of the brain. When atherosclerosis causes the blockage of arteries in the brain, it results in the stroke.

2. Peripheral Arterial Disease

Peripheral arterial disease is a condition which develops due to the insufficient or poor blood supply in the lower extremities. According to many studies, atherosclerosis is the most common cause of peripheral arterial disease. Most of the patients who develop the symptoms of this disease are due to atherosclerosis as it affects the entire cardiovascular system. Cigarette smoking is the main risk factor that is associated with peripheral arterial disease and there is a strong relationship between these two. For those who smoke, the risk of developing peripheral arterial disease doubles than those who do not smoke. Other risk factors that are involved in this disease include diabetes, high blood pressure, high cholesterol, hyperlipidemia, etc.

3. Vasculitis

It is a disorder that is caused by the inflammation within the walls of affected blood vessels. Any vessel in the part of the body can be affected by this disease. Vasculitis are basically of three types, a first type is an acute form that can be caused by infection, exposure to chemicals, etc. and generally, it does not require treatment. The second type of vasculitis can be caused by diseases such as arthritis or any type of cancer. Lastly, a type of vasculitis that can be caused by its own means and is not linked to any illness. Fever and weight loss are the general symptoms of vasculitis and it generally affects the heart, arteries, kidney, skin, nervous system, joints, etc..

Some natural ways to Improve Blood Circulation

  • Eat a balanced diet
  • Do regular exercise
  • Drink plenty of water
  • Maintain cholesterol level

Blood circulation is the movement of blood throughout the body and when this circulation of blood is affected due to any reason, the entire human body suffers. It plays a vital role in the proper functioning of the organs of the body. Share this post with your family and friends and create awareness. Stay Safe, Stay Healthy!!
