Respiratory System — Flashcards

The _____ pressure across the lungs is calculated as alveolar pressure minus intrapleural pressure

Central chemoreceptors respond indirectly to increased _____ and directly to decreased pH

The _____ respiratory group is primarily responsible for expiration and is not active during normal, quiet breathing

O2 is carried in blood in two forms: _____ (2%) or bound to hemoglobin (98%)

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

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

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

_____ chemoreceptors are located in the carotid bodies and aortic bodies

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

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