ventilation requires: pressure changes adequate atmospheric 02 clear air passages compliance and recoil intact respiratory center and chemorecptors |
|
What is diffusion and what is required for diffusion to occur?
|
diffusion is the movement of 02 from an area of greater concentration to an area of lower concentration
diffusion requires: adequate atmospheric 02 healthy alveolar-capillary membrane adequate surface area adequate pulmonary circulation |
|
What is perfusion and what is perfusion influence by?
