Which of the following is NOT a function of veins?

• A. Transporting oxygenated blood
• B. Returning deoxygenated blood to the heart
• C. Serving as a reservoir for blood
• D. Regulating blood temperature

Answer: (A)

The function of transporting oxygenated blood is primarily the responsibility of arteries, not veins. Arteries carry oxygen-rich blood away from the heart to various tissues and organs throughout the body. In contrast, veins are responsible for returning deoxygenated blood back to the heart after the oxygen has been delivered to the tissues. The other functions of veins include returning deoxygenated blood to the heart, which is crucial for maintaining proper circulation. Veins also serve as a reservoir for blood, holding a significant volume of blood in the circulatory system, which can be mobilized as needed. Additionally, veins play a role in regulating blood temperature by allowing blood to flow close to the skin surface, where heat can be exchanged with the environment. Therefore, the role of transporting oxygenated blood is not a function of veins, making it the correct choice in this question.
