An operational definition is developed so that a variable can be measured or manipulated in a concrete situation.
A conceptual definition is the theoretical meaning of a variable.
These are physiological measurements, but the terms within the stem of the question are not defined physiologically. A physiological definition would provide an accurate description of the concept on a biologic level.
The conceptual definition can sometimes be a theoretical definition.
