Blood Vessel Walls

The structures that form the boundaries of blood vessels, consisting of layers including the endothelium, smooth muscle, and connective tissue.

Elastic Arteries

Arteries that contain elastic fibers in their walls, allowing them to stretch and recoil as blood is pumped through them by the heart.
