Anatomy of the heart:
The heart is one of the most basic organs of the body. This muscular organ is the size of a human fist and is responsible for transporting blood and nutrients to the organs of the body. First, it sends deoxygenated blood to the lungs, where the blood is purified and free of carbon dioxide and other substances and returns to the heart. The heart again delivers blood with oxygen and nutrients to all the organs of the body.
The human heart is made up of 4 cavities, each of which has different functions: two cavities in the upper part of the heart that receive blood and two cavities in the lower part that are responsible for draining blood.
The amazing thing here is that both parts are active simultaneously and they contract and expand and create a rhythmic beat. This beat can be felt in the parts of the body where the vein has passed through the surface of the skin. Wrist, neck. In fact, the pulse is the heartbeat that is felt. When you feel your pulse, it means that you have felt the rush of blood in the veins due to the pumping of blood by the heart.
Every human heart can pump about 8 pints of blood continuously throughout the body.
At rest, the heart beats 60 times per minute, and it may happen 100 times per minute, which can be changed by factors such as exercise, lack of water, the use of certain drugs, and emotional factors. People who have a larger body have a faster pulse. The heart, blood, and blood vessels make up the cardiovascular system or circulatory system, which we will learn more about in the following article.
The heart has many complexities and at the same time it is very amazing.
One of the important points that can be mentioned about the anatomy of the heart is the valves that exist in the heart. There are 4 of these valves and their task is to ensure that the blood moves in only one direction. Better by the name of this valve. And get to know their location:
– Aortic valve: somewhere between the aorta and the left ventricle
– Mitral valve: somewhere between the left atrium and the left ventricle
– Pulmonary valve: somewhere between the right ventricle and the pulmonary artery
– Tricuspid valve: between right atrium and right ventricle
The opening and closing of these valves creates a sound that is known as the sound of the heart, and sometimes this sound can be used to diagnose the health of the heart or the presence of heart disease.
Electrical system of the heart:
In order for the blood to be pumped at the right time and in the right direction, coordination between the heart muscles is required, and the task of this coordination is with the electrical pulses.
Blood vessels of the heart:
The heart has 3 types of blood vessels as follows:
1- Artery: Arteries receive blood containing oxygen from the heart and deliver it to other organs of the body. Arteries are very strong and stretchy and also have muscles. Arteries are connected to smaller vessels called atrioles.
2- Veins: These types of blood vessels direct oxygen-deficient blood to the heart, and the closer they get to the heart, the larger they are. Veins have thinner walls than arteries.
3- Capillaries: These vessels are also referred to as the smallest vessels and are responsible for connecting the arteries to the smaller veins. Due to the fact that they have a very thin wall, it is possible for them to exchange compounds such as carbon dioxide, oxygen, nutrients and nutrients with body tissues.
According to the said material, we realized that the heart is a very necessary and powerful organ for the body and human life is very important. The heart can pump nutrients and oxygen to the organs. Now imagine that this does not happen and the heart does not pump and the blood does not reach the organs. That is, the heart does not beat, at this time the blood does not reach the brain and it is possible to die within a few minutes. It means that the person loses the ability to speak, has no breathing and has no heartbeat. At this time, CPR will be very helpful for the person. Calling 115 and CPR (if known and performed) greatly increases the chance of a person’s survival.
Now that we are familiar with the anatomy of the heart and its wonders, it is better to discuss some diseases and ways of diagnosis and tools that can be used to help diagnose patients.
One of these tools to help diagnose the disease is echocardiography, which in this article is also known as echo Doppler.
Doppler echo is a diagnostic method to identify some heart diseases. Of course, it is an integral part to diagnose the disease. By using Doppler echo, the speed and direction of blood can be determined.
The doctor assures the patient that the use of echo Doppler is completely safe and uncomplicated, and with the results obtained from its examination, he can treat the problems created for the patients with drugs or get another diagnosis for the disease by taking other tests.
Now it is better to know what is Echo Doppler and which people need it?
We will explain it to you with a simple example. Remember the sound of an ambulance when it approaches you and then moves away from you. You will notice the frequency of the generated sound, which is weak when it is far from you and the closer it gets to you, the frequency becomes stronger The same technique is used to measure the blood flow in the ventricles, atria and heart valves. The amount of blood that comes out with each heartbeat shows the function of the heart. With the help of echo Doppler, you can find out the health of the heart or the presence of problems in any of the valves and walls of the heart.
When a person has symptoms or complications of heart problems, the doctor prescribes an echo Doppler for him. The following symptoms cause an echo Doppler to be prescribed:
-Shortness of breath and swelling in the legs, which are signs of heart failure (heart failure is a disease in which the heart is unable to send oxygen-rich blood to other organs). With the use of echo Doppler, it is possible for the doctor to find out if the heart can pump well or not.
– Diagnosing the size of the heart, with an increase in blood pressure, there is a possibility of heart enlargement or heart failure or leakage of the heart valves, as well as an increase in the thickness of the ventricles, which can be treated on time by doing an echo Doppler.
