Answer:

The process that is not properly matched with its description is:

  • External respiration: CO2 diffuses into the blood stream.

Explanation:

Although external respiration effectively involves carbon dioxide (in addition to oxygen) since it refers to the exchange of carbon dioxide and oxygen that takes place between the blood and the environment, during this process what happens is that carbon dioxide is sent to the environment and oxygen is taken from the environment (about 78% of the air) to diffuse into the bloodstream, which is exactly the opposite of what the option says.
