as a function of
a term expressing correlation. in graphs of functional relationships between two variables, changes in one variable associated with changes in another (drug dose) are represented.

control

Feedback
In this context, in a series of events, what happens in a later event alters events that preceded it.

The amount of time that must pass for the amount of drug in the body to be reduced by half
Interact
