Arteries have thick, elastic walls because they carry blood away from the heart under high pressure. The heart pumps oxygenated blood into the arteries, and the thick walls help withstand and accommodate the force generated by this pumping action. The elasticity allows arteries to expand and contract, facilitating the smooth flow of blood throughout the cardiovascular system. This structural adaptation ensures that the arterial system can efficiently distribute oxygenated blood to various organs and tissues in the body, supporting the metabolic needs of cells while maintaining the integrity of the circulatory system under the pressure generated by the heart.
