Question

Why is diffusion insufficient dummy new oxygen requirements of miley cellular organisms like humans?

Answer 1

$\huge\mathfrak{Answer:-}$

⭕ Diffusion is insufficient to meet the oxygen requirements of multi cellular organisms like humans because of the following reasons :-

● Multi cellular organisms like humans have a very higher degree of organization of body. In other words we can say that they have complex body structure.

● Moreover, diffusion is a very slow process so it is insufficient.

Answer 2

In multicellular organisms like human beings diffusion is insufficient to meet the oxygen requirements of the body because of the following reasons :

• Diffusion is a very very slow process. Thus it can't fulfil the requirements of our body.

• The oxygen in human beings will have to travel last distances inside our body to reach each and every part of the cells.

• The volume of human body is so big that oxygen cannot diffuse into all the internal cells of the human body quickly.

• Also this is the reason for why the respiratory pigments are present in multicellular organisms also.
