The _____ center is located in the upper pons and inhibits inspiration

When lung volume is _____ than FRC, there is a net collapsing force on the lung-chest wall system

Breathing as an involuntary process is controlled by the _____ and pons of the brain stem

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

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

Elastic recoil is _____ proportional to compliance and directly proportional to elastance
