Modifications of this basic design account for the five types of blood vessels and the structural and functional differences among the various vessel types. WebThe tunica interna is the innermost layer and is composed of endothelial cells, which line the artery and provide a smooth surface for the blood to flow through. Arterioles are small branches of arteries that deliver blood to the capillaries. They are much smaller in diameter than arteries and have the same three layers of tissue.
