Final answer:
Blood is transported from the right side of the heart to the lungs in the pulmonary circuit.
Step-by-step explanation:
In the pulmonary circuit, blood is transported from the right side of the heart to the lungs. The right side of the heart pumps deoxygenated blood into the right and left pulmonary arteries, which carry the blood to the lungs.
In the lungs, the blood gives up carbon dioxide and picks up oxygen, becoming oxygenated, before it returns to the heart through pulmonary veins.
