The incorrect statement about blood vessels is:<br /><br />b. Muscular arteries and arterioles have multiple layers of elastin fibers which gives them recoil-like property.<br /><br />Explanation:<br />Muscular arteries and arterioles do have some elastin fibers, but they are primarily composed of smooth muscle cells. The recoil-like property is mainly due to the elastic fibers found in the tunica media layer of larger arteries, such as the aorta and pulmonary arteries.
