Answer:
Right ventricle, lungs, left atrium
Explanation:
The pathway of blood in the heart and lungs follows this order:
The body -> Superior and inferior vena cava -> Right atrium -> tricuspid valve-> right ventricle-> pulmonary semilunar valve -> pulmonary artery -> lungs-> pulmonary vein -> left atrium-> bicuspid valve -> left ventricle- aortic valve-> Aorta-> the body
So not counting the valves and the vessels, the best answer would be the first option.
It would also be good to remember that unoxygenated blood starts in the right side of the heart and the oxygenated blood starts in the left side of the heart.
Ventricles pump blood and atria receives blood. The right atrium receives blood from the lungs, while the left atrium receives blood from the body. The left ventricle pumps blood towards the body, while the right ventricle pumps blood towards the lungs.
