What is the primary function of arteries?

Arteries perform the vital role of carrying blood away from the heart to various parts of the body. This function is crucial because it ensures that oxygen-rich blood reaches tissues and organs, supplying them with the necessary nutrients and oxygen needed for cellular processes. As blood flows through the arteries, it is under high pressure, which allows it to travel efficiently throughout the circulatory system. While veins return blood to the heart, the primary role of arteries is to serve as conduits for blood moving away from the heart, making option C the accurate choice in this context.
