3.From the right ventricle, deoxygenated blood goes to the lungs for oxygenation through the pulmonary artery.

4.Inside the lungs, gaseous exchange takes place.

5.From the lungs, oxygenated blood goes to the left atrium through the pulmonary vein.

6.From the left atrium, oxygenated blood goes to the left ventricle.

7.From the left ventricle, oxygenated blood is pumped into the aorta so that it can be supplied to different body organs/tissue/cells.
