In our class of Biology we have been studying the gas exchange. After learning some its characteristics, we have made a chart. Here it is.
|Inspired Air||Expired Air|
|Oxygen||21%||16%||Respiration (Raw materials)|
|Carbon Dioxide||0.04%||4%||Respiration (Waste products)|
|Depends on the environment or atmosphere|
|Dust||Variable||Few, or no dust||Ciliated cells|
