Where does blood go after it picks up oxygen in the lungs?

Blood picks up oxygen in the lungs, which comes from the air people breathe. The blood containing oxygen is pumped from the lungs to the left side of the heart. The heart then pumps this oxygen-rich blood all over the body. The body's cells remove the oxygen from the blood cells and use it as energy. The blood cells then return to the right side of the heart, which pumps the blood to the lungs through the pulmonary arteries. In the lungs, the blood picks up more oxygen, and the whole cycle begins again.

Blood is pumped into the lungs by the right lower chamber of the heart, called the right ventricle. It then returns to the left upper chamber, called the left atrium, and flows into the left ventricle, which pumps it to the rest of the body.
