What type of blood do all arteries, except the pulmonary vein, carry?

All arteries, with the exception of the pulmonary arteries, carry oxygenated blood from the heart to the body’s tissues. This oxygen-rich blood is essential for supplying oxygen and nutrients to the cells. The primary function of the arteries is to transport this oxygenated blood under high pressure, ensuring adequate delivery to the various organs and systems in the body.

In contrast, the pulmonary arteries carry deoxygenated blood from the heart to the lungs, where it becomes oxygenated. Therefore, understanding that most arteries carry oxygenated blood highlights their role in maintaining the body's overall function and health.
