The video tutorial explains the structural differences between arteries and veins, highlighting the presence of smooth muscle layers in arteries and their rigid walls. It discusses the use of elastic staining to reveal the internal elastic lamina in arteries and contrasts this with veins, which lack such structures and have thinner, collapsible walls. The tutorial also covers how to identify blood vessels based on color and structure, noting that arteries are more likely to have a network of vasa vasorum compared to veins.
