Question 1.
Which of the following conditions will result in vasodilation ofthe arterioles?
A. increase H+; decrease O2; increase CO2
B. decrease H+; decrease O2; increase CO2
C. increase H+; increase CO2; increase O2
D. decrease H+; increase O2; increase CO2
Question 2
Which of these is demonstrated by the oxygen-hemoglobindissociation curve?
The greater the PO2 of the blood, the greater the dissociationof O2 from hemoglobin?
At normal resting systemic arterial PO2, hemoglobin is almost100% saturated with oxygen
At normal resting systemic venous PO2, only about 75% of thehemoglobin is in the form of deoxyhemoglobin
More additional oxygen binds to hemoglobin when going from a PO2of 60 to 80 mm Hg, than is added when going from a PO2 of 20 to 40mmHg
As PO2 increases, the saturation of hemoglobin with oxygenincreases linearly

1 Answer B decrease H ions decrease O2 Incresae CO2 Reason When the level of oxygen in our body get reduced the volume of CO2 would be greater There are many factors that are associated with these condition Whenever CO2 level is in high the H ions level would get reduced All these See Answer
