what law states that the force that stretches the vascular wall is proportional to the diameter of the vessel times the blood pressure?
Critical Closing Pressure, Laplaceâs Law and Compliance Critical closing pressure â Pressure at which a blood vessel collapses and blood flow stops Laplaceâs Law â Force acting on blood vessel wall is proportional to diameter of the vessel times blood pressure Vascular compliance â Tendency for blood vessel volume to increase as blood pressure increases â More easily the vessel wall stretches, the greater its compliance
