Question

If the partial pressure of oxygen in the lungs is 100 torr and in the tissues is 20 torr, how does this affect hemoglobin's oxygen affinity?

Accepted Answer

Hemoglobin has higher oxygen affinity in the lungs due to higher partial pressure of oxygen.

Answer

Hemoglobin has higher oxygen affinity in the tissues due to lower partial pressure of oxygen.

Answer

Hemoglobin has lower oxygen affinity in the lungs due to higher partial pressure of oxygen.

Answer

Hemoglobin's oxygen affinity is unaffected by changes in partial pressure of oxygen.
