PATHOLOGY

Detailed explanation-1: -Arteries and arterioles have thicker walls than veins and venules because they are closer to the heart and receive blood that is surging at a far greater pressure (Figure 2).

Detailed explanation-2: -Blood is pumped from the ventricles into large elastic arteries that branch repeatedly into smaller and smaller arteries until the branching results in microscopic arteries called arterioles.

Detailed explanation-3: -These are blood vessels that carry oxygenated blood from the heart to the tissues. These have thick-walled and narrower lumens because they carry blood from the heart with great pressure.
