Initial pressure 80 mmHg b. End pressure 0 mmHg c. Vessel length = 250 mm d. Viscosity3 e. Vessel radius 1.5 mm 2. Calculate the resistance the vessel has (label will be mmHg min/L) Using the data above, what is the new vascular Resistance if the radius changes to 2.75 mm? 3. 4. Using the same data from question #1, what happens to the Resistance if the vessel length becomes 32 mm?

Explanation / Answer

1) Resistance of the vessel wall is calculated according to the equation,

deltaP/Q (deltaP is the pressure difference and Q is the flow through vasculature)

The relationship between deltaP and radius of the vessel is given by the formula,

deltaP = (8muLQ)/(piR2)

Where mu is dynamic viscosity

L is length of the vessel

Q is flow rate

R is radius of the vessel

(80-0) = (8)(3)(0.25)Q/(3.14x0.75x0.75x 10 -6)

Q = (80)(1.77 x 10 -6)/6

= 23.6 x 10 -6

Resistance = deltaP/Q

= 80/23.6 x 10-6

= 3.39 x 10 6
