Vessel Elastic

In this image we see a representation of a sectioned elastic artery. Elastic arteries are vessels that can handle a great deal of pressure, such as the aorta, that must take the pressure directly from the constant beating of the heart. There are three main layers, beginning with the tunica intima, which is surrounded by the innermost elastic layer. The tunica media is much more volumetric and full of elastic fibers running in parallel fashion and provide most of the functional elasticity. The last layer, the tunica adventitia, then surrounds the main elastic layer.
