A ventilation system is needed in order to obtain oxygen for living organisms and to get rid of carbon dioxide. Surface diffusion utilized by many smaller organisms is not sufficient in supplying the oxygen needs of the body. It is also needed to maintain a concentration gradient in the alveoli.

What is a nervenet?

Do multicellular organisms have tissues?
Yes! All multi-cellular organisms contain specialized cells. Specialization is the reason they become multi-cellular. Multi-cellular organisms are differentiated from other eukaria and prokaria in that, rather than living individually or in convenient colonies, they MUST be multi-cellular to survive.
