Quizplus · Accepted Answer

Arteries have the thickest muscular walls among the given options, which allow them to constrict and dilate to regulate blood pressure and control blood flow. Capillaries are the smallest and thinnest vessels and lack smooth muscle, while veins have thinner muscular walls than arteries and contain valves to prevent backflow. Lymphatic vessels also have smooth muscle, but their walls are not as thick as arteries.
