PLC Development Environment Using GX Developer. In the C64 Series, the user PLC development environment is supported using MELSEC PLC. development tool, which is Mitsubishi integrated FA software MELSOFT series (GX Developer). This manual explains system configurations user PLC development environment using GX.
Critical Closing Pressure, Laplaceâs Law and Compliance Critical closing pressure â Pressure at which a blood vessel collapses and blood flow stops Laplaceâs 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
The vena cava has a thinner wall and a wider lumen than the aorta because of the lower blood pressures it has to deal with . Arterial blood pressure will be higher than venous blood pressure. The force generated by the heart as it pushes blood out requires thick vessel wall so it does not rupture. The vena cava simply carries blood back to the heart, there is much less force/pressure in the vena cava.
