Which blood vessels carry oxygen-rich blood away from the heart?

Veins
Capillaries
Arteries
Venules

The correct answer is: Arteries

Arteries are the blood vessels responsible for carrying oxygen-rich blood away from the heart to the rest of the body. They are equipped with thick, elastic walls that help withstand the high pressure of blood being pumped directly from the heart. When blood is oxygenated in the lungs, it returns to the heart and is then distributed through the arteries, ensuring that oxygen reaches all tissues and organs that need it for metabolic processes. In contrast, veins carry oxygen-poor blood back to the heart, while capillaries facilitate the exchange of oxygen and carbon dioxide between the blood and tissues. Venules serve as small vessels that collect blood from capillaries before it flows into the veins. Understanding the functions of these different types of blood vessels is crucial for recognizing how blood circulates within the body and the roles that each component plays in maintaining healthy bodily function.
