Respiratory Physiology - Part 6
Test your basic knowledge of respiratory physiology by taking this simple quiz.
(1)   A lower numerical value of oxygen (O2) P50 indicates a higher hemoglobin affinity for O2. Note: O2 P50 is the oxygen partial pressure (PO2) at which 50% of hemoglobin molecules are saturated with O2.
(2)   A lower numerical value of oxygen (O2) P50 indicates a lower hemoglobin affinity for O2. Note: O2 P50 is the oxygen partial pressure (PO2) at which 50% of hemoglobin molecules are saturated with O2.
(3)   The O2 P50 value of fetal hemoglobin is smaller (in numerical value) than the O2 P50 value of meternal hemoglobin. Note: O2 P50 is the oxygen partial pressure (PO2) at which 50% of hemoglobin molecules are saturated with O2.
(4)   Fetal hemoglobin has a lower affinity for oxygen (O2) than maternal hemoglobin.
(5)   Which of the following decrease(s) the affinity of hemoglobin for oxygen (O2)?
