Gas exchange — Flashcards

The lung diffusing capacity, DL, _____ in pulmonary fibrosis due to increased wall thickness (Δx)

Decreases in temperature cause the O2-hemoglobin dissociation curve to shift to the _____

O2 is carried in blood in two forms: dissolved (2%) or _____ (98%)

The HCO3- in red blood cells (from H2CO3) is transported into the plasma in exchange for _____

Shifts of the O2-Hb dissociation curve to the _____ occur when there is decreased affinity of hemoglobin for O2

_____ in temperature cause the O2-hemoglobin dissociation curve to shift to the right

DLCO may be used to estimate the extent to which _____ passes from the air sacs of lungs into blood

CO2 binding to hemoglobin favors the _____ form, thus _____ Hb affinity for O2

High altitudes indirectly cause the O2-hemoglobin dissociation curve to shift to the _____

In the steady state, the respiratory quotient, R, is normally equal to _____
