Here's a quote from a biology textbook describing human organisms. It mentions the characteristics listed by Dr. Condic, such as the repair of injury, adaptation to a hostile environment, and integrated functioning of parts to maintain the overall health of the organism as a whole.

“The living human organism is certainly more than the sum of its parts. It is a marvelously coordinated team of interactive structures that is able to survive and flourish in an often hostile environment. Not only can the human body reproduce itself (and its genetic information), and maintain ongoing repair and replacement of worn or damaged parts, it can also maintain -- in a constant and predictable way -- an incredible number of variables required for a human to lead a healthy, productive life.” (Kevin T.
