Which vessels carry oxygenated blood?

Arteries are responsible for carrying oxygenated blood away from the heart to the various tissues and organs in the body. This is essential for delivering the oxygen that cells need for metabolism and overall functioning. Arteries have thick, muscular walls that are designed to withstand the high pressures generated by the heart as it pumps blood.

While pulmonary veins also carry oxygenated blood, their function is specific to transporting blood from the lungs back to the heart after it has been oxygenated. However, in the general context of the question, arteries are the primary vessels known for this role throughout the body. Veins typically carry deoxygenated blood back to the heart, and capillaries serve as the sites of exchange between blood and tissues, but they do not actively carry oxygenated blood in the same way arteries do.
