Healthy Work System and Heart Function

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

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

The human heart is the size of a fist, divided into four parts, namely the right and left atrium, and the right and left chambers. Each heart space is separated by a layer of walls called the septum.

Blood is pumped through these parts. To ensure blood flow, there are valves that can be opened and closed. All valves have a duty to maintain blood flow in the right direction. There are four valves in the heart, which are:

• Mitral valve, located between the left atrium and left ventricle. This valve usually has two valves, therefore it is also called a bicuspid valve.
• Aortic valve, located between the left ventricle and aorta or artery.
• The tricuspid valve is located 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

Every part of the heart's anatomy has its own function. The following is a more detailed explanation.

Right porch

Inside the right foyer is dirty blood. Dirty blood is oxygen-poor blood, which enters the right atrium through the superior and inferior vena cava. From the right atrium, blood is pumped into the right ventricle. In the heart of the fetus, there is a hole in the right atrium to allow blood to flow directly into the left atrium. This is important for fetal circulation, because the fetus's lungs cannot function, so the fetus will draw clean, oxygen-rich blood directly from the mother. After birth, the baby's lungs enlarge and begin to function. The hole will close and form the boundary between the right and left porches.

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 cabin is under the right atrium and next to the left ventricle.
Dirty blood flowing through the right atrium will pass through the tricuspid valve to reach the right chamber. This blood is pumped into the lungs through the lung valves and flows through the pulmonary arteries.
If this part of the heart is not functioning properly, so you can no longer pump efficiently, you may 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 heart's left ventricle is located below 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 ventricular heart when pumping blood. If this happens continuously, the function of the left ventricle in pumping blood throughout the body may be affected.

Because of the importance of heart function, it is very appropriate for us to maintain it by adopting a healthy lifestyle, among others, eating lots of vegetables and fruits, exercising regularly, and most importantly, not smoking. If you experience heart dysfunction, immediately consult a doctor for treatment.
