BLOOD CIRCULATION, ILLUSTRATION
The blood enters into the superior and inferior vena cavae, arrives into the right atrium, the tricuspid valve opens to expels it into the left atrium, it winds up by the pulmonary valve into the pulmonary artery, comes back by the pulmonary veins on both sides in the left atrium, passes by the mitral valve to arrive into the left atrium, be expelled into the aortic valve toward the aorta to provide oxygen to the entire body. The heart has three layers, a superficial envelope named pericardium, a muscular envelope called myocardia, and one of them covers the inside, it is the endocardium. The septum is a vertical barrier that separates the two sides of the heart. The same drawing without the arrows : 2019308
