Healthy Work System and Heart Function

The main function of the heart is to pump blood throughout the body. As a means of transportation in the body, blood is tasked with carrying nutrients and oxygen needed by the organs of the body, as well as transporting residual substances. The heart and blood vessels form the cardiovascular system to ensure our survival. A normal, healthy heart is supported by strong muscle tissue 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, which is almost the size of a fist, is divided into four parts, the right and left atrium, and the right and left chambers. Each cardiac chamber is separated by a layer of walls 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 valves are tasked with keeping blood flowing in the right direction. There are four valves in the heart, namely:

• Mitral valve, located between the left atrium and the left ventricle. This valve normally has two valves, hence it is also called a bicuspid valve.
• Aortic valve, located between the left ventricle and the aorta or artery.
• The tricuspid valve, is between the right atrium and the right chamber, and has three valves.
• Pulmonary valve, located between the right ventricle and pulmonary artery.

Cardiac Function By Parts

Each part of the anatomy of the heart has its respective functions. The following is a more detailed explanation.

• Right porch

Inside the right porch is dirty blood. Dirty blood is oxygen-poor blood, entering the right atrium through the superior and inferior vena cava. From the right atrium, blood is pumped into the right ventricle. In the fetal heart, there is a hole in the right atrium to allow blood to flow directly to the left atrium. This is important for fetal circulation, because the fetal lungs have not been able to work, so the fetus will draw 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 porch right and left.

• The right cubicle

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 respiratory process. The booth is under the right atrium and beside the left cubicle. Dirty blood flowing through the right atrium will pass through the tricuspid valve to reach the right chamber. This 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 can experience right heart failure.

• Porch left

This part is responsible for receiving clean blood from the lungs. Clean blood is blood that contains oxygen. Clean blood enters the left atrium through the veins or pulmonary veins. This blood is then pumped into the left ventricle through the mitral valve.

• Left Cubes

The left ventricle of the heart is located under the left atrium 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. Conditions of high blood pressure can cause the muscles of the left ventricle to enlarge and harden, due to 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 for us to maintain it by adopting a healthy lifestyle, among others by consuming lots of vegetables and fruits, exercising regularly, and above all not smoking. If you experience interference with heart function, immediately consult a doctor to get treatment.
