Working system and healthy heart function

The main function of heart is to pump blood throughout the body. As a means of transportation in the body, blood carries the nutrients and oxygen needed by the body's organs, while transporting residual substances.  The heart and blood vessels form the cardiovascular system to ensure our survival.

A normal and healthy heart is supported by strong muscle tissues and works well in pumping blood. The heart that beats continuously in pumping blood, is able to drain more than 14,000 liters of blood per day.

The human heart is almost as small as the fist, divided into four parts, the right and left porch, and the right and left chamber. Each of these heart rooms is separated by a wall layer called a septum.

Blood is pumped through these parts. To ensure blood flow flow, there are valves that can open and close. All the valves are in charge of keeping the blood flowing in the right direction. There are four valves in the heart:

  • The mitral valve, located between the left porch and the left chamber. This valve normally has two valve leaves, hence also called the bikuspid valve.
  • The aortic valve, located between the left chamber and the aortic or the pulse trunk.
  • Tricuspid Valve, located between the right porch and the right chamber, and has three valve leaves.
  • The pulmonalist valve, located between the right chamber and the pulmonary artery.
  • Heart functions based on parts
  • Each part of the heart's Anatomy has its own function. Here's an explanation in more detail.


Right Porch

In the right foyer there is dirty blood. Gross blood is the blood of poor oxygen, enters the right foyer through the superior and inferior vein cava. From the right porch, the blood was pumped into the right chamber. At the heart of the fetus, there is a hole in the right foyer to allow blood to flow directly to the left foyer. It is important for fetal circulation, since the fetus's lungs have not been able to work, so the fetus will take a clean blood-rich oxygen directly from the mother. After birth, baby's lungs inflate and start functioning. The hole is closed and makes a boundary between the right and left foyer.

Right room

This is a responsible part of pumping dirty blood to the lungs so that carbon dioxide can be exchanged for oxygen through the respiratory process. Rooms are under the right foyer and next to the left room.
The dirty blood flowing through the right foyer will pass through the tricuspid valve to get to the right chamber. The blood is then pumped into the lungs through the pulmonary valve and runs through the pulmonary artery.
If this part of the heart is not functioning properly, so it can no longer pump efficiently, you could experience the right heart failure.

Left Porch

This section is responsible for receiving the blood clean from the lungs. Clean blood is blood that contains oxygen. Clean blood enters the left porch through a vein or pulmonary vein. This blood is then pumped into the left chamber through the mitral valve.

Left Chamber

The left chamber of the heart is located beneath the left porch and separated by mitral valves. The left chamber is the thickest part of the heart and is tasked with pumping clean blood throughout the body. The condition of high blood pressure can cause the left chamber muscles to enlarge and harden, due to the increased workload of the Left chamber of the heart in pumping blood. When this happens continuously, the function of the left chamber in pumping blood throughout the body can be interrupted.

Thus the importance of heart function, so we have to keep it by applying healthy lifestyle, among others, with a lot of vegetables and fruits, exercise routine, and which is mainly not smoke. If you experience impaired heart function, immediately consult a doctor for treatment.
