Question

6. Which of the following conditions favor edema formation?

a. lymphatic blockage
b. thrombophlebitis (venous clot)
c. decreased plasma protein concentration
d. greatly increased capillary pore size

7. Assume that three vessels with identical dimensions are combined into a network of one vessel followed by a parallel combination of the other two and that a pressure (Pi) is applied to the inlet of the first vessel, while a lower pressure (Po) exists at the outlet of the parallel pair.

a. Find the overall resistance of the network (Rn) if the resistance of each vessel is equal to Re.

b. Is the pressure (Pj) at the central junction of the network closer to Pi or Po?

c. Use the basic flow equation to derive an equation that relates the pressure drop across the input vessel (Pi Pj) to the total pressure drop across the network (Pi Po).

8. Given the following data, calculate an individual’s total peripheral resistance (TPR):

Mean arterial pressure, A = 100 mm Hg
Central venous pressure, PCV = 0 mm Hg
Cardiac output, CO = 6 L/min

Explanation / Answer

ans 6 - Edema is called the swelling of lymph nodes which is due to the lyphatic blockage which is the main cause of edema.

ans.8 total peripheral resistance = mean arterial pressure - mean venous pressure / cardiac output.

( 100 - 0 ) / 6 = 16.6 mm of Hg.
