<prompt> Which of the following increases turbulence in blood flowReynolds number less than 2000Decrease in velocity of bloodDecrease in density of bloodIncrease in diameter of blood vessel  <response>: The flow of blood Laminar or turbulent depends on- Fluid density S- Tube diameter D- The velocity of the fluid V- The viscosity of fluid nThis can be expressed by Reynolds number R SDVnNormal flow is laminar. But if the velocity crosses a critical limit Critical velocity flow becomes turbulent. If R2000, flow is turbulent.
