Step 3
From the right ventricle, the blood flows through the pulmonic valve into the pulmonary artery.
Step 4
The right and left pulmonary arteries carry unoxygenated blood to the right and left lungs for gas exchange.
Step 5
The blood releases carbon dioxide as waste and picks up a fresh supply of oxygen.
Step 6
The oxygenated blood flows through fpur pulmonary veins from the lungs into the left atrium.
