Struggling with this:
“Explain why a parallel flow gas exchange system would be less efficient than a counter-current gas exchange system” (it’s only 3 marks)
This is for A-level Biology btw

As with a parallel flow , equilibrium will eventually be reached. Therefor there will not be a high conc gradient of oxygen across the whole length, minimising diffusion
