What are the exchange vessels of the circulatory system, where nutrients, wastes, and hormones are transferred between blood and tissues?.
Venules.
Capillaries.
Arterioles.
Veins.
The Correct Answer is B
The correct answer is Choice B.
Choice A rationale:
Venules are small vessels that collect blood from the capillaries and transport it to the veins. They are not primarily involved in the exchange of nutrients, wastes, and hormones.
Choice B rationale:
Capillaries are tiny vessels that branch out from arterioles to form networks around body cells. They are the primary sites for the exchange of gases, nutrients, and waste between blood and tissues.
Choice C rationale:
Arterioles are small branches of arteries that lead to capillaries. They primarily regulate blood pressure and blood flow, not the exchange of substances.
Choice D rationale:
Veins carry deoxygenated blood back to the heart. They are not the primary sites for substance exchange.
