Question

Which two arteries are equipped with valves?

Answer 1

Arteries:

1. The blood vessels called arteries are responsible for delivering oxygen-rich blood from the heart to the body's tissues.
2. Typically, arteries lack valves.
3. However, there are valves on the two arteries exiting the right and left ventricles that stop blood from flowing backward.
4. Aortic and pulmonary valves are typically regarded as heart valves.
5. The aortic valve opens and the mitral valve shuts when the left ventricle contracts, allowing blood to flow into the aorta.
6. Additionally, the valves aid in the blood's struggle against gravity to return to the heart.
