CHAPTER 11
QUIZ CH 11:
1. c) 30 to 60 breaths per minute
2. c) Oxygen saturation in the arterial blood
8. Dalton’s law e) Partial sum of pressures to the total
pressure in the mixture of gases
2. TLC = 25 * 104 * 0.5/15 = 833.33 cubic centimeter
3. maximum gas volume of the bellows = 3.14 * 152 * 10 = 7065 cm3 = 7.06 liters;
Voltage at the max height of the potentiometer = 12/7.06 * max gas volume in liters = 1.7
* 7.06 = 12 V
4. Partial pressure of gas C = 0.35 * 500 = 175 psi
11. IRV = VC – TV – ERV = 4.1 – 0.7 – 1.1 = 2.3 liters
12. The rate of blood flow is directly proportional to the fourth power of the radius of the
vessel. If the radius is reduced by ½, the flow is reduced by 1/16 (i.e., flow rate is 15/16 =
0.94 ml/sec in the swollen tube).
13. Gas pressure is inversely proportional to the fourth power of the radius of the vessel.
So the pressure is 1.2 * 16 = 19.2 cm of H2O in the swollen tube.
