Anatomy of the heart is an important thing that needs to be known to be able to understand the workings and disorders that can occur in your heart. Because, each specific location of abnormalities in the heart, will determine the disruption that occurs and its effect on the body.
The heart is an organ with a heavy task and works very hard. Every minute, an adult’s heart beats 60-100 times under normal conditions.
Know the Main Parts of the Heart
The heart is located in the middle of the chest, on the left side of the body, precisely below the rib cage. The heart is flanked by the left and right lungs. Anatomy of the heart and its size in each person is different.
There are four main chambers of the heart, each filled with blood with different oxygen content. The two upper chambers of the heart are called the atria (porches of the heart). This space is filled with blood returning to the heart. The left atrium receives oxygen-rich blood from the lungs, while the right atrium receives oxygen-poor blood from the entire body.
Then the two chambers at the bottom of the heart are called the ventricles (chambers of the heart). The left ventricle receives blood from the left atrium, and will pump blood to the body’s main blood vessels called the aorta. From this aorta, oxygen-rich blood will be distributed throughout the body including the brain, muscles and other cells. While the right ventricle, which receives blood from the right atrium, pumps blood to the lungs.
Between the heart chambers, there is a separator in the form of muscles with thick walls called the septum. On the surface of the heart, there are coronary arteries that provide blood to the heart muscle.
When the heart beats, there is blood flow in and out of the heart through blood vessels, known as the heart’s circulatory system. Blood will be carried to the lungs through the pulmonary arteries, then oxygen-rich blood is pumped throughout the body through the aortic veins. While blood from the body that has lack of oxygen will return to the heart through the vena cava, and blood that has received oxygen, will be channeled from the lungs to the heart through the pulmonary vein.
Talking about the heart, not separated from the coronary system, which is composed of blood vessels. Coronary arteries provide oxygen-rich blood to the heart muscle. Branches of the coronary arteries surround the surface of the heart and channel blood through the heart muscle, which is then distributed to all heart cells. While the coronary veins are responsible for carrying oxygen-deprived blood out of the heart muscle.
The heart is wrapped in a bag called the pericardium. Around the heart there is a neural network as a regulator of complex signals for heart contraction and relaxation.
How the heart works
The task of the heart in the process of pumping and supplying blood throughout the body is not simple. The right atrium receives blood from the entire body through the vena cava, which then flows into the right ventricle. Blood from the right ventricle is pumped out of the heart into the lungs, to exchange carbon dioxide with oxygen. Oxygenated blood is pumped into the left atrium, then to the left ventricle, which is then flowed throughout the body through the aorta.
For blood to flow properly, the heart has a valve. Valves that help blood flow from the atria to the ventricles are the mitral and tricuspid valves. Meanwhile, valves that function to control the flow of blood leaving the heart are the aortic valve and pulmonary valve.
The four valves keep the blood moving in one direction. The valve closes quickly so the blood doesn’t turn in the opposite direction.
Disturbances That Must Be Cautioned
As you age, the performance of the heart organ will decrease and increase the risk of serious illness related to heart function. Disorders or diseases affecting the heart organ can also occur not because of the aging process, and can be life-threatening.
Some disorders that can occur in the heart, including:
Coronary heart disease
Coronary heart disease, is influenced by obstruction of blood flow from the coronary arteries that supply blood to the heart. This condition is generally caused by atherosclerosis, which is the narrowing of the arteries caused by the formation of plaque in the walls of blood vessels, thereby reducing the amount of blood flow.
Through a stethoscope, abnormal sounds from the heart can be heard which may be caused by disruption in blood flow. This generally indicates an abnormality in the heart valve.
Heart attacks occur due to blood clots in the coronary arteries, which can interfere with the performance of the heart muscle and can be fatal.
Cardiomyopathy is a heart disease related to the heart muscle (myocardium). This condition is generally caused by a weakening of the heart muscle, so that the heart does not pump blood optimally to other parts of the body. Cardiomyopathy can cause heart failure, heart valve problems and other complications.
Heart failure occurs when the heart cannot pump blood as the body needs.
Keep Your Heart Healthy
Applying a healthy lifestyle is one of the requirements in maintaining optimal heart performance. You also need to start smoking, remembering that smoking is one of the main causes of coronary heart disease. In addition, reduce the intake of alcoholic drinks.
Then, start to be more active in order to maintain physical fitness. Do aerobic activity about 150 minutes per week, or 30 minutes for 5 days a week. Maximize with a balanced diet that is low in fat and high in fiber to maintain ideal body weight. Being overweight can increase the risk of heart disease.
You should also read food packaging labels when you shop. As much as possible minimize the consumption of products that contain too much salt. Also reduce saturated fat for example by limiting fried snacks and replacing full cream milk with low-fat milk. You are not forbidden to eat meat, but limit the portion and prioritize lean meat that is roasted or grilled compared to fried.
No less important is managing stress appropriately. Brisk walking can reduce the pressure you feel and help clear your mind.
Love your heart. Make changes right now by avoiding things that can be detrimental to health, as well as starting to run new habits that are beneficial for maintaining the performance and anatomy of the heart in optimal condition.
