Where does the blood from the right atrium flow to?

Introduction
Blood from the right atrium normally flows into the right ventricle and subsequently enters the pulmonary artery. If abnormalities in cardiac blood flow are detected in daily life, it is recommended that patients promptly visit a hospital to undergo relevant examinations, such as electrocardiogram (ECG) and echocardiography, to rule out the possibility of heart disease. When necessary, timely intervention can be implemented to prevent serious impacts on health.
Normally, blood from the right atrium flows into the right ventricle and subsequently enters the pulmonary artery. A detailed explanation is as follows:
Under normal conditions, during the diastolic phase of the heart, all venous blood from the body returns to the right atrium. From there, blood flows through the tricuspid valve into the right ventricle. Upon contraction of the right ventricle, the blood passes through the pulmonary valve into the pulmonary artery. The pulmonary artery then carries the blood through the pulmonary capillaries and pulmonary veins back to the left atrium. Finally, blood from the left atrium flows through the mitral valve into the left ventricle, completing the cardiac circulatory cycle. If abnormalities occur during this process, they typically affect the blood flow within the heart, potentially causing ischemia and hypoxia.
If abnormal blood flow in the heart is detected in daily life, it is recommended that patients promptly visit a hospital to undergo relevant diagnostic tests, such as electrocardiogram (ECG) and echocardiography, to rule out the presence of heart disease. When necessary, timely intervention can help prevent serious impacts on health.
