Answer:
- human respiratory system
- x= rings of cartilage y= alveolar sac z= lungs
- this diagram is important for a human being because
- respiration is a complex process during which digested food is oxidized to release chemical energy it involves a series of reaction all of them catalyzed by specific enzyme
- the energy is stored in ATP molecules
4. ring of cartilage help to ensure that the air passage does not collapse
