vasculature

Question 1

what does Reynold’s number give an indication of?

Answer 1

whether blood flow is likely to be laminar or turbulent

Question 2

what is the the equation for reynolds number?

Answer 2

Re = (velocity of flow) x (radius of vessel) / viscosity

Question 3

what are the four things that therefore increase the likelihood of turbulence?

Answer 3

high velocity flow
large diameter vessels
low blood viscosity
abnormal vessel wall

Question 4

what is the equation which connects the tension in a blood vessel to pressure and radius of the vessel (LaPlace’s Law)?

Answer 4

T=PR
