The heart is an indispensable and important organ. Function of heart It is quite a challenge, the heart diagram Labeled below. Provides information on all types of rooms the heart valves that help pump blood from one part of the body to heart to another. To learn more about how, keep reading! heart works.
4 heart and circulatory chambers
The shape of the human heart It looks like an upside-down pear, weighs 7 to 15 ounces, and is slightly larger than a fist. It is located in the middle of the rib cage, slightly to the left behind the sternum, between the non-weight-bearing parts. The heart It is one of the most important organs in the body. the human It is a muscular pump that pumps blood throughout the body; it fights about 72 times per minute to pump oxygen-rich blood to different parts of the body.
Atria and ventricles
There are four video cameras in your house. heart These are the left atrium, right atrium, left ventricle, and right ventricle.
- Your upper chambers. heart atria and the lower chambers represent the ventricles.
- Oxygen-deprived blood flow heart Through the right atrium, blood goes first to the arterial chambers, then non-oxygenated blood goes through the pulmonary arteries. The left atrium receives oxygenated blood from the non-pulmonary, then to the left ventricle, and from there to the aorta, and then to various parts of the body.
Valves ensure that the blood flows in one direction.
Your heart There are four valves in the ________________, whose main function is to regulate the blood flow through the aorta. the heart . Every heart diagram These valves are clearly marked on the label. These valves ensure that blood flows in only one direction. Different valves function differently.
- The tricuspid valve is located between the right ventricles heart It allows blood to flow from the right atrium to the right ventricle.
- The pulmonary valve is located between the left pulmonary artery heart and his right ventricle. When the right ventricle contracts, it opens, allowing blood to flow into the left pulmonary artery.
- The mitral valve also has two valves, arranged in such a way that they divide the left ventricle of the heart. heart And your left atrium. heart The aortic valve allows oxygen to erupt into the left heart chamber when the left atrium is pinched.
- The aortic valve isolates the aorta of the left heart chamber and controls blood flow from the heart chamber to the rest of the body.
Blood Vessels
- Blood vessels help transport blood. heart These barrels connect the other organs of your body to yours. heart .
- The most important function of these vessels is to absorb oxygen. the heart And bring oxygen-rich blood from non-obese the heart to the rest of your body.
Blood vessels are more than that, they are a network circulate blood through the entire trunk. there are two arteries and veins.
- Arteries: This type of blood vessel takes oxygen and the heart It transports it to the capillaries. Arteries are very tough from the outside but smooth on the inside. the heart There are three arteries: the pulmonary artery, the aorta, and the coronary artery. The pulmonary artery is the only artery that drains oxygen-poisoned blood from the right side heart to your lungs; the aorta is considered the critical artery. the heart It then transports oxygen-rich blood to the rest of the body. The coronary arteries are connected to the coronary arteries the heart And transport gorgeous oxygen-rich blood to you! heart muscles.
- Dear: They look a lot like arteries, but they are not so strong, especially because they do not transport blood at the highest pressure.Veers receive waste products after the exchange of oxygen and carbon dioxide.3 Veins the heart Long veins, coronas, and coronary sinclas. The pulmonary veins transport oxygen-rich blood to the left. heart vena cava. the heart and the coronary sinus receives oxygen and poor blood and brings it into the right atrium.
Blood circulation.
Your circulatory The system moves oxygen-rich blood to all tissues in the body. Your heart blood is pushed out when squeezed together; it moves in two cycles. In the system cycle, you are positioned by the left side of your heart , the blood circulates your body and supplies air to organs, tissues, and other structures. By the pulmonary loop located on your right side. heart Blood moves toward the non-lung loop, producing carbon dioxide and getting fresh air.
In the systemic loop, oxygen-rich blood flows from the nonpulmonary loop to the left upper left atrium or video camera. heart The polecam fills the mitral valve one time – with blood, and the blood flows to the left ventricle. Your left side blood heart When the heart chamber contracts during the heartbeat, it descends into the aorta. The aorta is about 2.5 cm wide and guarantees a luxurious supply of oxygen to the body cells. The applied blood moves and ends up in two veins. Vena Cava Superior, which receives blood from your upper body, and Vena Cava inferior, which receives blood from your lower body.
These veins bring you to the correct atrium of your bosom. heart From there your blood goes through the tricuspid principle to the fair Hind Room. The ventricles squeeze and send blood to the pulmonary arteries. The pulmonary artery sends blood to the lower abdomen, from where oxygen-rich blood returns to the left ventricle and the process continues.
Appearance of the Human Heart
A heart diagram Marked provides a lot of information about the structure of your heart. heart It covers the walls of your heart. heart . The wall of the heart There are three distinct layers, these are the myocardium, epicardium, and endocardium. Here is a closer look at these three layers
Epicardium
Your outer layer heart cane is called the epicardium and forms a fairly fine serous membrane at the base. The membrane provides lubrication and protection to your outer heart , as you can see in heart diagram labeled.
myocardium.
Just below the epicardium is a relatively larger, more complete layer called the myocardium. The middle layer of this muscle of heart wall contains the material of the heart. a huge portion of your thickness and mass. heart The wall is made of cardiac muscle. Layers are considered parts the heart Its blood passes through your myocardium.
endocardium.
Beneath the myocardium is yet another layer called the endocardium. This layer surrounds your inner lobe. heart It is usually quite slippery. The most important role of this smooth, delicate layer is to protect the Myocard heart It also helps prevent the formation of deadly blood clots.
Watch this video to learn more about the structure of the myocardium. of human heart .
Different Types of Heart Disease
Coronary heart disease.
Arteries that return blood to the heart can become clogged by cholesterol. the heart The blockage can be caused by a buildup of cholesterol. This blockage causes coronary heart disease. These narrow arteries have every opportunity to develop a blood clot at a particular point in time. heart attack.
Myocardial Infarction.
Also called heart An attack, myocardial infarction, is considered the result of an unexpected blockage of a coronary artery. The blockage reduces the amount of air entering the arteries of the heart. heart This is fatal to the coronary arteries. the heart muscle.
Cardiac rhythm disorders.
A condition characterized by irregular or abnormal heart rhythms caused by changes in the guidance of the electrical impulses by the arteries. heart Open-air rhythm disorders can be benign or have life-threatening consequences.
Chronic
You develop this condition when you are heart very stiff or very weak in pumping enough blood to your body. If you notice these signs, such as shortness of breath or swelling in your legs, this may indicate loading. heart failure.
Myocarditis.
You develop this condition when you are heart muscles become inflamed. In most cases, this inflammation is thought to be the result of a viral infection.
Cardiac arrest
It is a type of heart Cardiac arrest, since it refers to the sudden loss of function of your heart .
Sudden cardiac death
When someone dies as a result of cardiac arrest or sudden loss of of heart function, this sudden cardiac death is called This condition is also called cardiac arrest.
Heart Valve Disease.
The heart has four valves. heart A problem with one of them leads to the development of one a heart disease. If they are not treated early heart the heart valves may accumulate disease. heart failure.
Heart Noise.
When your doctor listens to your heart rate with a stethoscope, he makes that may hear abnormal heart sound. This condition becomes heart generally benign hormesis. Sometimes it is possible heart disease as well.
