Explanation:
Detailed explanation-1: -The human aortic and elastic (conducting) arteries have between 40 and 70 elastic lamellae; they expand in response to blood flow and then have passive elastic recoil that allows for the maintenance of diastolic pressure.
Detailed explanation-2: -The aorta, where the artery wall contains a high proportion of elastin fibres, permits significant distension during systole. During diastole, blood is pushed forward through the arterial tree due to elastic recoil ensuring blood flow in one direction and smoothing of blood flow.
