Understanding how the heart works

The heart is an organ that is responsible for pumping blood throughout the body to supply oxygen, so that all organs function normally. If does not get oxygen, the body tissue will be damaged and die. Let's understand the car a heart work in pumping blood , and any diseases that can interfere with work this organ.

The heart works nonstop to support the circulatory system. In addition to the heart as its center, this system also consists of blood vessel tissue, such as arteries (arteries), veins (veins), and capillaries.

Understanding how the heart works

Identify How it works Heart

There are four the heart space involved in the work of the heart to pump blood from and to the whole body. The four chambers of the heart are the atrium (heart chambers) right and left at the top of the heart, and the ventricles (chambers of the heart) right and left at the bottom of the heart.

The right foyer of the heart will receive dirty blood or slightly containing oxygen (because it binds to carbon dioxide) from the body, then this dirty blood is flowed into the right chamber. Then by the right chamber, dirty blood will be pumped into the lungs to exchange carbon dioxide with oxygen.

After this exchange, the blood that has been filled with oxygen will be pumped into the left foyer, then proceed to the left ventricle the heart to flow throughout the body through large blood vessels (aorta).

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

  • Tricuspid valve, which is located between the right foyer and the right chamber of the heart.
  • Pulmonary valve, which is located between the heart and blood vessels to the lungs.
  • Mitral valve, which is located between the left foyer and the left ventricle of the heart.
  • The aortic valve, which is located between the heart and large blood vessels towards the whole body.

Interference Work Heart

Disorders of the heart can appear in any part of the heart, starting from the heart muscle wall , heart valves, to the heart's electrical conductors which cause abnormal heart rhythms. Any disturbance in the heart can affect the workings of the heart in pumping blood.

Disorders can also occur in coronary arteries, namely blood vessels that provide blood and oxygen intake to the heart muscle. Coronary blood vessels can be blocked by plaque, so that blood flow to the heart muscle is blocked. This condition is called atherosclerosis.

The blockage in the coronary arteries will eventually cause heart disease, if the heart muscle has experienced lack of oxygen. When the supply of blood and oxygen to an area of ​​the heart is completely blocked, a heart attack will occur. Symptoms include chest pain such as being crushed, and radiating to the neck, jaw, or arms, cold sweat, shortness of breath, and weakness.

To maintain the work of the heart and minimize the risk of heart problems, you are advised to exercise routine, eating healthy and nutritious foods, reducing salt consumption, maintaining ideal body weight, controlling blood pressure and cholesterol levels, getting enough sleep, not smoking, and limiting drinking alcoholic beverages.

You are also advised to do an examination routine to the heart doctor, especially if you feel any symptoms of heart problems, such as chest pain, shortness of breath, fatigue, and swelling in the legs.
