Which of the following is a primary characteristic of arteries?

Thin walls
Carry blood towards the heart
Carry oxygenated blood
Transport nutrients

The correct answer is: Carry oxygenated blood

Arteries are primarily characterized by carrying oxygenated blood away from the heart to various tissues and organs throughout the body. This is crucial for delivering the essential oxygen and nutrients necessary for cellular functions. While pulmonary arteries are the exception, as they carry deoxygenated blood from the heart to the lungs for oxygenation, the general function of arteries is to transport oxygen-rich blood. The characteristic of having thin walls does not correctly apply to arteries, as they are typically thicker than veins to withstand the high pressure of blood pumped from the heart. Regarding the direction of blood flow, arteries carry blood away from the heart, not towards it, which distinguishes them from veins. Lastly, although some nutrients may be transported through arterial blood, that is not the primary role of arteries, which is centered around oxygen transport.
