In which direction do veins generally carry blood?
Answer and explanation
Correct answer: Toward the heart
The governing concept is circulation through blood vessels. Veins generally return blood from body tissues toward the heart, where it can be sent to the lungs or pumped onward. Their walls are thinner and pressure is lower than in arteries, so many veins contain valves that help prevent backward flow. The direction away from the heart defines arteries; therefore option A is correct.
