Elasticity Of Arteries

Arteries carry blood away form the heart the extremities and organs. They have typical three layer blood vessel wall structure with a thick tunica media. The walls of arteries are highly compliant due to the elastic fibres present. The wall thickness of the arteries varies in based on the proximity to the heart. The elasticity of arteries allows pressure absorption from the left ventricle of the heart as it pumps blood into the arteries. There are two significant types of arteries, elastic and muscular. Elastic arteries are the largest in the body and include the aorta and pulmonary trunk. The vessel walls are relatively thin in comparison to the overall size. They assist in propelling blood onwards while ventricles are relaxing by storing
