Similarly, this would result in a lower Reynolds number and therefore more laminar blood flow.

c
Reduced diameter of vessels
QuestionChoice
Reynolds number (Re) is used to indicate whether blood flow is likely laminar or turbulent. As Reynolds number increases, turbulent blood flow becomes more likely. Re = ( ( Velocity of flow ) x ( radius of the vessel ) ) / ( Viscosity ). Therefore according to the equation, the reduction in viscosity will result in a larger Reynolds number.

a
Reduced blood viscosity
QuestionChoice
According to the equation for the Reynolds number, this would result in a lower value and more laminar flow.
10004087
b
Low-velocity flow
QuestionChoice
This would result in more laminar blood flow and a lower Reynolds number as abnormal vessel walls result in increased turbulence.

e
Normal vessel walls
QuestionChoice
As observed in the Reynolds equation this does not directly contribute to blood flow.
