Extrapulmonary restrictive lung diseases are characterized by _____ A-a gradients

Increased pCO2 and resulting decrease of pH enhancing the release of O2 from hemoglobin is called the _____ effect

In _____-limited gas exchange, the gas does not equilibrate by the time blood reaches the end of the capillary

Slow waves originate in the _____, which serve as the pacemaker for GI smooth muscle

The _____ gradient is the driving force for the diffusion of a gas

In response to exercise, there is _____ venous CO2 content

The majority of CO2 transported in blood is in the form of _____ (90%)
