The main heart function is pumping blood throughout the body. As a means of transportation in the body, blood is responsible for carrying nutrients and oxygen needed by the body’s organs, while transporting waste substances. The heart and blood vessels form the cardiovascular system to ensure our survival.
A normal and healthy heart is supported by strong muscle tissue and works well in pumping blood. The heart beats continuously in pumping blood, capable of flowing more than 14,000 liters of blood per day.
The human heart, which is almost the size of a fist, is divided into four parts, right and left, and the right and left chambers. Each room of the heart is separated by a layer of wall called the septum.
Blood is pumped through these parts. To ensure the flow of blood flow, there are valves that can open and close. All these valves are responsible for keeping blood flowing in the right direction. There are four valves in the heart, namely:
The mitral valve, located between the left porch and the left ventricle. This valve normally has two valve leaves, hence it is also called a bicuspid valve.
The aortic valve, located between the left ventricle and the aorta or pulse.
The tricuspid valve is between the right foyer and the right chamber, and has three valve leaves.
The pulmonary valve, located between the right chamber and the pulmonary artery.
Heart Function Based on the Parts
Each part of the heart anatomy has its own function. Next is the explanation in more detail.
Inside the right porch is dirty blood. Dirty blood is oxygen-poor blood, entering the right porch through the superior and inferior vena cava. From the right porch, blood is pumped into the right chamber. In the fetal heart, there is a hole in the right foyer to allow blood to flow directly to the left foyer. This is important for fetal circulation, because the lungs of the fetus have not been able to work, so the fetus will take clean oxygen-rich blood directly from the mother. After birth, the baby’s lungs expand and begin to function. The hole will be closed and make a boundary between the right and left porch.
This is the part that is responsible for pumping dirty blood into the lungs so that carbon dioxide can be exchanged with oxygen through the breathing process. The booth is under the right porch and next to the left booth.
Dirty blood flowing through the right foyer will pass through the tricuspid valve to arrive at the right ventricle. This blood is then pumped towards the lungs through the pulmonary valve and runs through the pulmonary artery.
If this part of the heart is not functioning properly, so that it can no longer pump efficiently, you can experience right heart failure.
This section is responsible for receiving clean blood from the lungs. Clean blood is oxygenated blood. Clean blood enters the left foyer through a vein or pulmonary vein. This blood is then pumped into the left ventricle through the mitral valve.
The left ventricle of the heart is located under the left porch and separated by the mitral valve. The left ventricle is the thickest part of the heart and is responsible for pumping clean blood throughout the body. The condition of high blood pressure can cause the left ventricular muscle to enlarge and harden, because of the increased workload of the left ventricle in pumping blood. If this happens continuously, the function of the left ventricle in pumping blood throughout the body can be disrupted.
Thus the importance of heart function, it is fitting that we protect it by adopting a healthy lifestyle, including eating lots of vegetables and fruits, exercising regularly, and especially not smoking. If you experience interference with heart function, immediately consult a doctor to get treatment.
