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.

During when we are alive, oxygen is used to make atp, and atp is used to break cross-brdiges when we are relaxing / contracting our muscles. when a person is dead then there is no oxygen but the body can still produce atp via anaerobic glycolysis, when the glycogen is depleted then no atp is produce so the the cross bridges can no logner be broken that is why skeletal muscles lock
