Science


Exchange surfaces


Exchange surfaces are adapted in the following ways to make

the process as efficient as possible

 

⇒  They are thin – this reduces the diffusion distance and ensures the 

      substance diffuses across very quickly

⇒  A large surface area – this ensures that many substances can diffuse 

     across at the same time

⇒  Large blood supple – this maintains the diffusion gradient
