The correct answer is: out, away from

The prefix "ex-" signifies "out" or "away from." This term is commonly used in medical terminology and other fields to indicate a position or movement that is away from a place or point of origin. For instance, in the term "exhale," it describes the action of breathing air out of the lungs. Understanding this prefix helps to comprehend various terms and their meanings, enhancing communication within the medical billing and coding context, where precise language is vital. The other options deal with different concepts that do not align with the meaning of "ex-." By focusing on the correct definition, individuals can better interpret various medical terms and their applications.
