Answer
Diffusion
Explanation
## Step 1:Identify the process on how gases move within the human body, which is particularly from the lungs to the bloodstream and vice versa.## Step 2:Understand what different processes entail. ### *Osmosis* is a process where a solvent moves from an area of lower solute concentration to a region of higher solute concentration.### *Distillation* is a process of purifying a substance by heating it to its boiling point, capturing and cooling the resultant hot vapors, and then collecting the condensed vapors.### *Active transport* is the movement of molecules across a membrane from a lesser concentration area to higher concentration area that involves energy.### *Diffusion* is the movement of molecules from an area of high concentration to an area of lower concentration.### *Evaporation* is a type of vaporization that occurs on the surface of a liquid as it changes into the gaseous state.## Step 3:From these definitions, we conclude that *diffusion* is the most fitting process for this problem — it describes the way oxygen and carbon dioxide move between the lungs and the blood.
