Circulation and Gas Exchange - Biology 212 with Landys at Oregon State University - StudyBlue from classconnection.s3.amazonaws.com Minimise the distance for this diffusion, and maintain adequate concentration gradients for it. Although the primary sites of gas exchange are the alveoli, exchange of o2 and co2 also happens between blood and tissues. Gas exchange is the process by which oxygen and carbon dioxide (the respiratory gases) animals with small bodies exchange respiratory gases sufficiently through the body surface since fresh air is always flowing through the lung, the oxygen concentration can be maintained at a constant, high level.
Gas exchange is the physical process by which gases move passively by diffusion across a surface.
