In the cardiovascular system, what role do arteries play?

Arteries play a crucial role in the cardiovascular system by carrying blood away from the heart. This is vital for maintaining the flow of oxygen-rich blood to various tissues and organs throughout the body. When the heart pumps, it creates pressure that propels the blood through these vessels, ensuring that nutrients and oxygen reach the cells that need them for proper function and metabolism.

While other components of the cardiovascular system have their own important functions, the primary characteristic of arteries is this direct pathway for oxygenated blood (in the case of systemic circulation) or deoxygenated blood (in pulmonary circulation) away from the heart, allowing the body's systems to function effectively.
