The thickest walled vessels are arteries, as they have to endure a more forceful power, as the heart, pumps the blood with great force around the body.
aorta
Blood vessels are composed of three layers of tissue: tunica externa, tunica media, and tunica interna. The middle layer, tunica media, is composed of smooth muscle and is thickest in arteries because they need to accommodate the higher pressures created by the heart's pumping action which distributes blood throughout the body.
It depends whether it's a concave or convex lens. If it's a convex lens - the thickest part is at the centre. With a concave lens, the thickest part is around the edge.

arteries are thick walled blood vessels carring oxygenated blood from heart to the various parts of the body.pulmonary arteries act as veins and carry deoxegenated blood from the right auricle to the lungs,Thus it is different from the arteries
veins
The veins are neither strong nor thick of the blood vessels. On the contrary the veins are thin and thin walled. The arteries are strong and thick. They have to bear the pressure of the blood that comes from the heart.
When blood is pumped into the thin-walled blood vessels of the lungs, carbon dioxide is replaced with oxygen.

In anatomy, lymph vessels are thin walled, valved structures that carry lymph.
idk? O_O thats wat i want to know too :P
