$\large{\underline{\text{Question\;1\;:}}}$

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

$\large{\underline{\bigstar\;\sf{Answer\;:}}}$

We know, diffusion is a slow process and humans are multicellular organisms with complex body structure. So, diffusion is insufficient to meet the oxygen requirements of multicellular organisms. Also, the cells are not in direct contact with environment in multicellular organisms. Therefore, there are specialised tissues and organs to fulfill the requirements of oxygen in multicellular organisms like humans.
