Code TH H3.09.02.0.01010

An elastic artery (or large elastic artery or conducting artery) is an artery with a large number of collagen and elastin filaments in the tunica media, which gives it the ability to stretch in response to each pulse. This elasticity also gives rise to the Windkessel effect, which helps to maintain a relatively constant pressure in the arteries despite the pulsating nature of the blood flow. Elastic arteries include the largest arteries in the body, those closest to the heart. They give rise to medium-sized vessels known as distributing arteries (or muscular arteries).

The pulmonary arteries, the aorta, and its branches together comprise the body's system of elastic arteries.
