The tunica interna of an elastic artery has subendothelial laminas of elastic fibres. Its tunica media has many fenestrated elastic membranes alternating with smooth muscle fibres. An elastic artery also has external elastic lamina. Its tunica externa is thin and contains vasa vasorum.

Arteries contain elastic fibres. These are particularly abundant in the large conducting arteries, such as the aorta.

Arteries contain elastic fibres. These are particularly abundant in the large conducting arteries, such as the aorta.
The conducting arteries, which are the high pressure arteries (eg. aorta and pulmonary), are high in elastic fibres. These fibres store energy to help to push blood forward during diastole (heart relaxation).
The term Elastic Arteries usually refers to the ability of blood vessels to dilate and constrict freely.
The elastic walls helps regulate blood pressure.
Yes blood passes through Elastic Arteries, Muscular Arteries, and then Arterioles.
Elastic arteries are also known as conducting arteries because they carry large volumes of blood away from the heart. They are large vessels with diameters up to 2.5 cm (1 in.) (Figure 21-2). The pulmonary trunk and aorta, as well as their major branches (the pulmonary, common carotid, subclavian, and common iliac arteries), are elastic arteries. The walls of elastic arteries are extremely resilient because the tunica media contains a high density of elastic fibers and relatively few smooth muscle cells.
