29. Which of the following statements about blood vessels is incorrect? a. More than % 60 of the blood in our body is found in the veins. b. Muscular arteries and arterioles have multiple layers of elastin fibers which gives them recoil-like property. c. Arterioles provide the greatest resistance to the blood flow. d. Veins have valves to prevent backflow of blood. e Regulations of diameters (vasocon striction/vasodilation)of arterioles is done by increased/decreased sympathetic nervous system activity.

Cevap

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.
