Fick's lаw stаtes thаt the rate оf diffusiоn оf a gas = k x A x (P2 - P1)/D (where K is a constant, A is the area of the surface, (P2 - P1) is the difference in partial pressure of the gas on the two sides of the surface, and D is the thickness of the respiratory surface. How does Fick's law help explain why it is more difficult for an animal to obtain oxygen at high elevation compared to low elevation?
