Answer 32

40 mmHg

Question 33

PvCO2 normal value for venous blood

Answer 33

46 mmHg

Question 34

what are the general trends of changes in PO2 through the circulation?

Answer 34

in systemic venous blood stays same at around 40 mmHg, once enters pulmonary capillaries goes up to around 100 mmHg, drops slightly as mixed with pulmonary shunt blood then plateaus at just under 100 mmHg in systemic arterial blood, drops as in systemic capillaries and plateaus again at 40 when returns to systemic venous blood
