Question

why is diffusion insufficient to meet the oxygen requirements of multi-cellular organisms like humans?​

Answer 1

Answer:

ʏᴏᴜʀ ᴀɴsᴡᴇʀ✔️

Diffusion is insufficient to meet the oxygen requirement of multicellular organisms like human because all the cells are not direct contact in environment and diffusion is a slow process. Diffusion is too slow to cover the distance between the gas exchange surface and the sites where the oxygen is required.
