What is the flow of blood in the heart

Deoxygenated blood

Superior / Inferior vena cava -> Right atrium -> Tricuspid Valve -> Right ventricle -> Pulmonary semilunar valve -> Pulmonary Trunk -> Lungs

Oxygenated blood

Lungs -> 4 pulmonary veins -> left atrium -> mitral valve -> left ventricle -> aortic semilunar valve -> Aorta -> Body -> SVC/IVC
