Force of fluid on the walls of the arteries
WebArteries carry oxygenated blood away from your heart. They have thick walls and a muscular layer that keeps your blood moving. Arteries can be as wide as a nickel (about two centimeters).... WebAn artery is a blood vessel that conducts blood away from the heart. All arteries have relatively thick walls that can withstand the high pressure of blood ejected from the heart. However, those close to the heart have the thickest walls, containing a high percentage of elastic fibers in all three of their tunics.
