Elastic arteries

Step-by-step explanation

The Elastic arteries compensate when pressure changes occur during normal cardiac cycle. Elastic arteries are the largest arties in the body specifically those that are closest to the heart. They give rise to the so called Windkessel effect which helps in maintaining a relatively constant pressure that are in the arteries despite the presence of pulsating nature of blood flow. These arteries contain a large number of collagen and elastin filaments which gives them the ability to stretch in response to each pulse. They are larger compared to the muscular arteries. Because they are exposed to the highest pressure compared to other blood vessels, they are known to have the thickest tunica media which enables it to stretch and recoil and also the smooth muscle allows them to be able to constrict and dilate. Lastly, the elastic arties are called the pressure reservoir and that means they have a crucial role in the pressure changes that are occurring in normal cardiac cycle.
