3 steps in the process of oxygenation: - Answer-
ventilation, perfusion, and diffusion
Is inspiration an active or passive process? - Answer-
active; stimulated by chemical receptors in the aorta
Is expiration an active or passive process? - Answer-
passive; depends on the elastic recoil properties of the
lungs, requiring little or no muscle work
TRUE or FALSE: clubbing will not occur in patients with
asthma. - Answer-FALSE
