Verified step by step guidance

Understand the components of the circulatory system: The human circulatory system consists of two main circuits - the pulmonary circuit and the systemic circuit.

Identify the role of the pulmonary circuit: The primary function of the pulmonary circuit is to transport deoxygenated blood from the right side of the heart to the lungs.

Explain the process in the lungs: In the lungs, the blood releases carbon dioxide and picks up oxygen during the process of gas exchange.

Trace the path back to the heart: After oxygenation, the now oxygen-rich blood returns to the left side of the heart.

Differentiate from the systemic circuit: Contrast this with the systemic circuit, which carries oxygenated blood from the heart to the rest of the body and returns deoxygenated blood back to the heart.
