What is Peripheral resistance is inversely propoional to: and explain in detail?
Poiseuille-Hagen equation: (for the flow of a fluid in a rigid cylindrical tube) Q = P x (pr4/8el) Q = flow, P (or P1 - P2) = pressure difference between two points, r = radius of the tube, e = viscosity of the fluid, and l = length of the tube. By Ohm's law: Q = P/R; OR R = P/Q. {R = resistance} Thus, viscous resistance (R) can be given by combining the above two formula: R = (8el)/(pr4) Thus, viscous resistance is propoional to the viscosity (e) of the fluid and the length (l) of the tube. inversely propoional to the fouh power of the radius of the tube (blood vessel). Thus option A is correct.
