The body's most muscular and elastic blood vessels are the arteries. They have thick, muscular walls that allow them to withstand and regulate the high pressure of blood pumped from the heart. This muscularity also enables arteries to constrict and dilate, helping to control blood flow. Additionally, the elastic fibers in their walls help accommodate the surge of blood with each heartbeat.
