2. Arteries usually have relatively thick walls and elastic walls
3. It can tolerate high blood pressure, mainly from the heart.
4. The arteries closest to the heart have the thickest walls, with a high percentage of elastic fibers.

Reason:

2. The veins (blue) carry oxygen-depleted blood back to the heart.
3. The arteries begin with the aorta, the large artery that leaves the heart.
4. They usually carry oxygen-rich blood from the heart to various tissues of the body.
