DEOXYGENATED BLOOD returns to the RIGHT side of the heart by the Inferior/Superior Vena cavas(2 major VEINS- bring blood BACK to heart from upper & lower body) & the Coronary Sinus. Blood enters the RIGHT ATRIUM-goes through the TRICUSPID VALVE to the RIGHT VENTRICLE. PULMONARY CIRCULATION then occurs. Blood enters the PULMONARY ARTERY through the SEMILUNAR VALVES. Blood enters the LUNGS & goes to the ALVEOLI. The now OXYGENATED blood returns to the LEFT side of the heart via the PULMONARY VEIN. It enters the LEFT ATRIUM, goes throught the MITRAL/BICUSPID valve to the LEFT VENTRICLE then AWAY from the body by means of the AORTA.
