Detailed explanation-1: -Arteries have thick walls and are situated superficially in comparison to other blood vessels. Arteries are blood vessels, the network of pathways through which the oxygenated blood travels away from the heart to various cells, tissues, and organs of the human body.

Detailed explanation-2: -The wall of an artery consists of three layers. The innermost layer, the tunica intima (also called tunica interna), is simple squamous epithelium surrounded by a connective tissue basement membrane with elastic fibers. The middle layer, the tunica media, is primarily smooth muscle and is usually the thickest layer.

Detailed explanation-3: -The largest artery in the body is Aorta that pumps oxygenated blood into the body.

Detailed explanation-4: -The left ventricle has the thickest wall out of all the chambers. The left ventricle is responsible for pumping the blood towards the tissues of the heart. This is why more muscles contracting inside the left ventricle helps produce a higher force to move the blood towards the system.
