Respiratory System — Flashcards

The V/Q ratio at the base of the lung is normally _____, indicating wasted perfusion

In zone 2 of the lung, blood flow is driven by the difference between _____ and alveolar pressure

The gradient between PAo2 - PaO2 is known as the _____ and is normally 10 - 15 mmHg

Shifts of the O2-Hb dissociation curve to the _____ cause decreased unloading of O2 at tissues

Hysteresis occurs due to the need to overcome _____ forces during lung inflation (inspiration)

The oxygen-Hb dissociation curve is roughly flat when the Po2 is between _____ and 100 mmHg

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

_____ chemoreceptors are located in the carotid bodies and aortic bodies

_____ dead space can be measured by the single-breath N2 curve (Fowler's method).

The volume of the _____ zone of the lung comprises the "anatomic dead space"
