Process that is not properly matched with its description is: external respiration: CO2 diffuses into the blood stream

Respiration is the process by which O2 and CO2 diffuse into the blood and get out of the blood (gas exchange occurs). There are two types of respiration:

1. External respiration - gas exchange between the external environment and the lungs. This is what we call breathing. So the example above is not external respiration.

2. Internal respiration - gas exchange between the cells of the body and the blood
