Question

The next few questions have to do with the hemoglobin association curves.

choose from the following:

a. increase b. decrease c. not change

1. when hemoglobin moves into pulmonary capillaries surrounding the aveoli, its affinity for O2 will__________

2. When PCO2 increases in systemic capillary beds above set point, hemoglobin's saturation will__________-

3. An increase in capillary blood pH will lead to an_____ in hemoglobin/oxygen disassociation.

4. When the concentration of 2,3-DPG is lower than normal, the hemoglobin affinity for O2 will_________

1. When hemoglobin moves into pulmonary capillaries surrounding the aveoli, its affinity for O2 will b. decrease

2. When PCO2 increases in systemic capillary beds above set point, hemoglobin's saturation will b. Decrease

3. An increase in capillary blood pH will lead to an a. increase in hemoglobin/oxygen disassociation.

4. When the concentration of 2,3-DPG is lower than normal, the hemoglobin affinity for O2 will a. increase

Temperature, pH, PCO2, and DPG are the factors Influencing Hemoglobin Saturation:

Increase of temperature, PCO2, and DPG and decrease of pH: Decrease hemoglobin’s affinity for oxygen

Decreases of temperature, PCO2, and DPG and the increase of pH: Enhance oxygen unloading from the blood (act in the opposite manner).
