From the right atrium, it enters the right ventricle through the tricuspid valve. Pass through the lung half-moon valve from the right ventricle
From the pulmonary vein, blood flows into the left atrium. From the left atrium, blood flows through the mitral valve (mitral valve)
The blood path through the human heart consists of pulmonary circulation and systemic circulation. Deoxygenated blood flows through the heart in one direction, through the so-called superior vena cava, into the right atrium, then through the tricuspid valve into the right ventricle, and then through the pulmonary valve to the lungs Send the pulmonary artery. It then passes through the pulmonary vein from the lungs to the left atrium where it is delivered through the mitral valve to the left ventricle and then through the aortic valve to the aorta. In summary, this task is studying the function and structure of the cardiovascular system. It also defines charts of the circulatory system
Bottom: A schematic diagram of the blood path through the human heart, lungs and internal organs. Oxygenated blood is indicated by red, blue deoxygenated blood. Blood coming out of the stomach, spleen and intestine passes through the liver before returning to the heart. You can remove excess or harmful substances absorbed from these organs before the blood returns to the general circulation. The coronary artery appears at the maximum blood pressure point of the cardiovascular system. Over time, the arterial wall tends to lose its elasticity, which limits the amount of blood that can flow through them, thereby limiting the oxygen supply to the heart. Arteriosclerosis
