Understanding how the Heart works

The heart is the organ that is tasked with pumping blood throughout the body to supply oxygen, so that all organs function normally. If not getting oxygen, the body tissues will be damaged and die. Let's understand how the heart works in pumping blood, as well as what diseases can interfere with the work of the organ.

Understanding how the Heart works


The heart works relentlessly to support the circulatory system. Besides the heart as its center, the system also consists of vascular tissue, such as arteries, veins, and capillary vessels.

Recognizing how the heart works
There are four heart chambers involved in the work of the heart to pump blood from and throughout the body. The four heart chambers are the right and left atrium at the top of the heart, and the right and left ventricle (heart chamber) at the bottom of the heart.

The right porch of the heart will receive dirty blood or a small amount of oxygen (because it binds to carbon dioxide) from the body, then the dirty blood is flowing into the right chamber. Then by the right chamber, the dirty blood will be pumped to the lungs to process carbon dioxide exchange with oxygen.

After the exchange occurs, oxygen-filled blood will be pumped into the left porch, then proceed to the left chamber of the heart to be flowed throughout the body via a large vein (aorta).

These four heart chambers are separated by a heart partition, and are equipped by four valves. The heart valve function in helping the heart work is to regulate the direction of blood flow, so that blood does not flow back into the previous space. The four valves are:

Tricuspid Valve, located between the right porch and the right chamber of the heart.
The pulmonary valve, which lies between the heart and blood vessels towards the lungs.
The mitral valve, located between the left porch and the left chamber of the heart.
The aortic valve, which is located between the heart and large blood vessels to the whole body.
Cardiac work disorder
Disturbances in the heart can appear in any part of the heart, ranging from the heart muscle walls, heart valves, to the electrical conduction that causes heart rhythm abnormalities. Any disturbance to the heart can affect the way the heart works in pumping blood.

Interference can also occur in coronary arteries, which are blood vessels that give blood and oxygen intake to the heart muscle. Coronary veins can be clogged by plaque, so blood flow to the heart muscle is hindered. This condition is called atherosclerosis.

Blockages in the old coronary vessels will cause heart disease, when the heart muscle is already experiencing a lack of oxygen. When the supply of blood and oxygen to an area of the heart is completely obstructed, a heart attack will occur. The symptoms are painful chest pain, and they go up to the neck, jaw, or arms, cold sweat, breathlessness, and weakness.

In order to maintain heart work and minimize the risk of heart disorders, you are advised to exercise regularly, consume healthy and nutritious food, reduce salt consumption, maintain ideal body weight, control blood pressure and Cholesterol levels, adequate sleep, no smoking, and limiting drinking alcoholic beverages.

You are also advised to perform routine examinations to the cardiologist, especially if you feel any symptoms of heart disorders, such as chest pain, shortness of breath, fatigue and swelling in the legs.
