1. 20 subjects participate in a study of ardiopulmonary physiology. The pulmonary circulation of these subjects most likely has which fof the following characeteristscs compared w/ their bronchial circulation?
a) greater number of branches supplying the visceral pleura
b) larger number of asntomoses w/ interecostal arteries
c) larger percentrage of cardiac output
d) larger volume of nutrient blood to the conducting airways (WRONG )
e) lower volume, higher pressure system
previously healthy 54 yo man comes to the clinic because of lightheadedness for 6 hours. His symptoms began after skiing at a resort at an altitude of 9000 ft. he has been taking a carbonic anhydrase inhibitor since 2 days before arriving at the resort. His BP is 110/60 which sitting and 95/50 while standing. PE shows no other abnormalities. Which of the following is the most likely cause of his orthostatic hypotension?
a). High-alt. sickness
b). Hypovolemia
c). Hypoxia
