Q
Definition
A
States a relationship between the rate of diffusion at a constant temperature and 3 variables…
Concentration gradient, length of diffusion pathway and surface area
2
Q
Lung adaptations
A
Concentration gradient-lots of capillaries surround the alveoli
Length of diffusion pathway-alveoli are only 1 cell thick
Surface area-lungs are very large, millions of alveoli with folded surfaces
3
Q
Equation
A
Rate of diffusion is proportional to…
surface area x difference in concentration
Over the thickness of the gas exchanged surface
