Answer:
The Right ventricle and the Left atrium.
Explanation:
The pulmonary circulation loop starts in the right ventricle, where the
deoxygenated blood is. From there, the blood goes through the pulmonary semilunar valves and into the pulmonary trunk. The pulmonary trunk divides into two arteries, the left, and right pulmonary arteries. These arteries conduct the deoxygenated blood to the capillaries in the lungs where we exchange the CO₂ for O₂. Then, the oxygenated blood goes to the pulmonary venules and the pulmonary vein. The pulmonary vein conducts the oxygenated blood from the lungs to the left atrium of the heart. Lastly, the blood goes to the left ventricle, where the systemic circulation starts.
