Why Are the Walls of Arteries Thicker Than Veins
Arteries have thicker walls than veins because they must be able to withstand the tremendous pressure from a beating heart. This can be felt as a pulse. Pin On Biology Why Do Arteries Have Thicker Walls Than Veins. . In veins the pressure is much less and so thinner walls are present. Arteries have a great deal more smooth muscle within their walls than veins thus their greater wall thickness. This can be felt as a pulse. The vessel walls of veins are thinner than arteries and do not have as much tunica media. Because of this pressure the walls of arteries are much thicker than those of veins. Veins are wider than arteries which allows for a more efficient exchange of carbon dioxide and oxygen. Arteries have thick walls that carry blood from the heart todifferent parts of the body. The blood pumped out by the heart is under high pressure and to withstand this pressure arteries are thick-walled. Arteries ex...
