The process of respiration system would not function well if the lungs was made up of only one big alveoli.
<u>Explanation:</u>
The main role of alveoli is to help the lungs to breath, for ventilation, diffusion and perfusion. The process of respiration system would not function well if the lungs was made up of only one big alveoli.
Alveoli are tiny to help the flow of oxygen and carbon dioxide, it helps the oxygen flow into the lungs and remove the carbon dioxide. If the alveoli is just one and big, then it would be hard to flow the oxygen through lungs and remove the carbon dioxide.
Therefore, it is good to have many tiny alveoli than one big one or the rib cage that protect the lungs could go through some damages.
