The correct path of blood flow through the heart and lungs is a. left atrium, left ventricle, pulmonary artery, pulmonary vein, right atrium, right ventricle, aorta. b. right atrium, right ventricle, pulmonary vein, pulmonary artery, left atrium, left ventricle, aorta. c. left atrium, left ventricle, pulmonary vein, pulmonary artery, right atrium, right ventricle, aorta. d. right atrium, right ventricle, pulmonary artery, pulmonary vein, left atrium, left ventricle, aorta.

The correct answer is option D

The poor oxygenated blood is send to the right atrium and then to the right ventricle through the tricuspid valve which is then pumped to the lungs through pulmonary valve. The blood then enters pulmonary veins which empties the oxygen-rich blood from the lungs into the left atrium and then to the left ventricle through the open mitral valve
