Question

Why is diffusion insufficient to meet the oxygen requirement of multicellular organisms like humans ?

Answer:

Diffusion is unable to meet the oxygen requirements of multi-cellular organisms such as humans because diffusion is one of the slow processes. That is a lot of time is required for oxygen to circulate to all the cells of the body. ... Therefore, through diffusion, it becomes difficult for oxygen to reach all the cells.
