_____ in Pco2 cause the O2-hemoglobin dissociation curve to shift to the left

In the _____, hypoxia causes vaso-constriction

If a sharp object punctures the intrapleural space (_____), the intrapleural pressure becomes equal to atmospheric pressure

When using the alveolar gas equation, the respiratory quotient (R) is equal to the ratio of _____ / O2 consumed

Central chemoreceptors are stimulated by changes in _____ and Pco2 of the brain

The V/Q mismatch seen in pulmonary embolism can result in _____, which causes hyper-ventilation with consequent respiratory alkalosis

Central chemoreceptors are especially sensitive to the _____ of the cerebrospinal fluid

In zone _____ of the lung, blood flow (Q) is lowest

The volume of the _____ dead space plus the alveolar dead space comprises the 'physiologic dead space'

In _____-limited gas exchange, diffusion can be increased only if blood flow increases
