It's IGCSE but it probably isn't that different. I'm counting on you lads.

You cannot. I think the dots are just meant to show that it's muscle tissue.

Vein tissue is thinner and the lumen is wider than the artery - this means that veins transport blood at a lower pressure than arteries.

The lumen sizes differ and so do the muscle size, due to a difference in function of the two.

There are plenty of differences between arteries and veins. To name a few, arteries have a much thicker wall relative to their lumen - this is because the tunica media (the layer which contains smooth muscle and elastic tissue) is much thicker in arteries in veins. Veins have a much thinner wall relative to their lumen, however veins have a much thicker tunica adventitia (outer layer made of collagen) than arteries.
