Question

what is correct order of blood flow through the cardiovascular system

Answer 1

Superior vena cava / inferior vena cava -> right atrium -> tri cuspid valve -> right ventricle -> pulmonary semilunar valve -> pulmonary artery ->lung -> pulmonary vein -> left atrium -> bi cuspid valve -> left ventricle -> aortic semilunar valve -> aorta -> body parts .

Blood enters heart through two large vein superior and inferior vena cava carrying deoxygenated blood from body into the right atrium then it goes to right ventricle through tricuspid valve . Blood leaves the heart and move to lungs now pulmonary vein carries oxygenated bloid from lungs to left atrium of heart then to left ventricle through valve ( valves are important because they prevent back flow of blood ) . Now blood leaves heart through aortic valve into aorta and flow to th rest of body parts .
