Which of the following is a feature of artery?

Arteries have several distinctive features:

1. Thick Walls: Arteries have thicker walls compared to veins. This is because they need to withstand the high pressure of blood pumped from the heart.

2. Small Lumen: The lumen (inner open space) of an artery is relatively small to maintain high blood pressure.

3. Elastic and Muscular Tissue: Arteries are made up of more elastic and muscular tissue to accommodate the pressure and help in the blood flow.

4. Carry Oxygenated Blood: Except for the pulmonary artery, all other arteries carry oxygenated blood from the heart to other parts of the body.

5. No Valves: Arteries do not have valves (except for the semi-lunar valves found at the junction of the ventricles and the arteries). This is because the blood is under high pressure which prevents backflow.

6. Pulsatile Nature: As the heart contracts and relaxes, arteries expand and contract, creating a pulse that can be felt in various points in the body.
