Verified step by step guidance1
Identify the components of the pulmonary circuit, which includes the right side of the heart, pulmonary arteries, lungs, and pulmonary veins.
Understand that the primary role of the pulmonary circuit is related to the lungs and involves the exchange of gases.
Recognize that the pulmonary circuit carries deoxygenated blood from the right ventricle of the heart to the lungs via the pulmonary arteries.
In the lungs, gas exchange occurs where carbon dioxide is released from the blood and oxygen is absorbed into the blood.
The oxygenated blood is then returned to the left atrium of the heart through the pulmonary veins, completing the primary function of the pulmonary circuit.
