the heart
The heart is the muscle on which the entire body depends. The heart is the primary organ of the circulatory system. The heart pumps oxygen-laden blood to all members of the body by regular contractions and distribution through the blood vessels. The heart consists of four basic chambers and in each of these rooms There is a valve, and in this article we will show you the heart valves.
Heart valves
The valves are the corridors through which the blood passes from the heart to the body, from the lungs to the heart. The valve consists of several rigid rings and flexible cells that move in a way that allows them to close and open. It must be noted that the blood takes place within the heart and the body in one direction, Do not go back, the four heart valves are:
Meteral valve
The valve is the most important valve in the heart, and this valve is located in the left atrium. This is the place where blood is transferred from the lungs and is loaded with oxygen. The heart takes part of it and the remaining amount of it is pumped to the body.
Tri-balconies
The valve is called triangular balconies, because it consists of three balconies. This valve is located in the right half of the heart between the right ventricle and the right atrium. This valve prevents the return of the blood to the right ventricle. It also prevents the opposite blood flow between the two chambers of the heart. This valve, like the right ventricle rather than the normal pathway, causes serious and serious complications.
Pulmonary valve
It is also called the crescent valve. The valve is located between the pulmonary artery and the right ventricle. The pulmonary valve is composed of three openings. The valve’s role is to receive blood from the lung and transfer it to the heart. It also transfers oxygen-laden blood from the heart to the lung.
Aortic valve
This valve is the place where oxygenated blood is collected, so blood is pumped from the heart to the rest of the body.
Main problems exposed to valves
Heart valve diseases are one of the most serious diseases. Fever diseases are known to be defects or defects that lead to weak heart valves and thus inability to function as accurate blood pathways. These diseases can occur as a result of:
- The valve is not completely closed. This problem occurs in people with heart defects caused by problems during childbirth.
- Blockage of the valve, the result of accumulation of excess fat and high cholesterol in the blood, so as to block the passage of blood, and may result from this problem my heart death.
- Tightness of the valve, which may occur as a result of a birth defect, or an acquired heart disease, leading to heart disease and other organs in the body, due to dysfunction of the heart.
