This difference in concentration creates a concentration in gas exchange alveoli and the gradient … WebOxygen is absorped into the blood by the process of diffusion. A large surface area, short diffusion pathway (the distance the oxygen has to travel through) and large concentration gradient increases the rate of diffusion and therefore oxygen absorption. The lungs are made up of many tiny air sacs called alveoli. WebAdaptations of the Alveoli.
