Blood pressure varies all the time because of changes in heart beat, which becomes more energetic when it is influenced by adrenaline. Arteries need to have the capacity to expand so that they do not burst, at a time of unusually high blood pressure. So an elastic material is useful, since it has the capacity to stretch without breaking.

Arteries
When the artery walls lose their elasticity, this is called arteriosclerosis. When this happens, the body has a tougher time circulating blood.
The elasticity enables the arteries to change their diameter. Smaller means more pressure, larger means lower pressure.
The amount of muscle in veins and arteries varies in the sense that arteries are more muscular than veins to give them extra elasticity and strength to deal with surges of blood.

Arterial stiffness is a general term for the elasticity (or compliance) of the arteries. The hardening or stiffening of the arteries is called arteriosclerosis. The stiffness of arteries influences how hard the heart has to work to pump blood through the body.
Elasticity allows hormones to travel up AND down the bloodstream easier. (i.e. when the pituitary glands sends GH to the heart and lungs.) without elasticity, we would quickly develop bronchitus after consuming foods or drinks. HOPE THIS HELPS!
