How do arteries and veins connecting with the lungs differ from arteries and veins connecting with other organs?

Arteries and veins connecting with the lungs differ from those associated with other organs primarily in their function and structure. Pulmonary arteries carry deoxygenated blood from the heart to the lungs for oxygenation, while pulmonary veins return oxygenated blood to the heart. In contrast, systemic arteries transport oxygen-rich blood from the heart to the rest of the body, and systemic veins return deoxygenated blood back to the heart. Additionally, the pulmonary circulation operates at lower pressure compared to the higher pressure found in the systemic circulation.
