What system does the heart valve belong to?

1. Heart valves belong to the cardiovascular system.

2. Heart valves are located between the atria, ventricles, or ventricles and arteries. The primary function of heart valves is to prevent blood pumped during heartbeats from flowing backwards out of the atria or ventricles. Heart valves are divided into atrial valves and semilunar valves, with atrial valves being further divided into mitral valves and tricuspid valves, and semilunar valves being divided into pulmonary valves and aortic valves.

3. Under the influence of factors such as fatigue, genetics, obesity, and hyperlipidemia, heart valves may become abnormal, leading to valve abnormalities and diseases. Common heart valve diseases include mitral valve regurgitation, tricuspid valve regurgitation, aortic valve regurgitation, and aortic valve stenosis.

4. When patients experience suspicious symptoms such as palpitations, shortness of breath, fatigue, worsening fatigue, etc., it is recommended to seek medical attention promptly and undergo electrocardiogram, echocardiography, coronary angiography, and other examinations under the guidance of a doctor. If abnormalities are found, it is recommended to undergo symptomatic treatment under the guidance of a doctor.
