Practice Test 4

What is the correct sequence of blood flow through the heart?

Blood enters the heart on the right side, collecting in the right atrium. After moving through the right ventricle, blood leaves the heart through the pulmonary artery to travel to the lungs to release carbon dioxide and absorb oxygen. The blood returns to the left side of the heart, through the pulmonary vein, going to the left atrium, then through the mitral valve to the left ventricle. Lastly, the blood leaves the heart through the aorta.
