1.	Do you think that the stiffness / rigidity of blood vessel is something to do with circulation?
Answer» The walls of the arteries are stiff/rigid. They are made up of muscle fibre and are elastic. When heart pumps blood into the arteries, the blood enters with a pressure into the arteries. Their walls will stretch and this enables the arteries to withstand the increase in the pressure without bursting.
