What is the primary function of arteries in the circulatory system?

The primary function of arteries in the circulatory system is to carry blood away from the heart. This is crucial for maintaining circulation and ensuring that oxygen-rich blood is distributed throughout the body to supply tissues and organs with the necessary nutrients and oxygen they need for proper functioning.

Arteries are structured with thick, elastic walls that can withstand and help regulate the high pressure of blood being pumped from the heart. This adaptation is essential for the efficient transportation of blood. Meanwhile, the other choices refer to functions that do not accurately describe the role of arteries; for instance, the veins are responsible for returning blood to the heart, while processes like filtering and gas exchange occur in other components of the circulatory system and respiratory system, respectively.
