What vessels are primarily responsible for the exchange of nutrients and waste products?

Veins
Arteries
Capillaries
Valves

The correct answer is: Capillaries

Capillaries are the smallest blood vessels in the body and are responsible for the exchange of nutrients and waste products between the blood and the body's tissues. Veins and arteries are larger vessels that help transport blood throughout the body, but they do not directly participate in the exchange of nutrients and waste products. Valves are structures within veins that help prevent blood from flowing backwards, and while they are important for proper circulation, they are not responsible for exchanging nutrients and waste products. Therefore, option C is the best answer.
