Question
the alveolar space.
blood leaving the heart through the aorta.
actively contracting muscle tissue.
all of these.
2.
The total pressure of gas in the alveolar space is 100 mm Hg. The partial pressure of CO2 is 45 mm Hg. What is the maximum partial pressure of oxygen?
5 mm Hg
20 mm Hg
55 mm Hg
90 mm Hg
3.
What happens to gas exchange in a low oxygen environment?
carbon dioxide may build up in the body
oxygen cannot move from the alveolar space into the blood
nitrogen may build up in the body
all of these
the alveolar space.
Explanation / Answer
1.partial pressure of oxyegen at alveolar space 104mmhg,
Blood leaving heart thriugh capillary -75mmhg.actively contracting muscle -40 mmhg ,so the correctv
Ans.is option (C).
2 partial pressure of oxygen=total pressure -partial pressure of co2 =100-45=55mmhg.so ans.is option (C)
3.inlow oxygen environment co2 will build up in the body.because there is impairment of gas exchange.
4normal urine ph range 1.010-1.030,tranparant,presence of urochrome, phis 0.60.
Albumin is not found in normal conditin.so ans.is option (D)
