Negative feedback system?
Elevate hormones whose levels are low and reduce hormones whose levels are high.
Cross-reactivity?
A different compound than intended is able to act upon a receptor.
Four hormone response classifications during exercise?
Acute response during exercise, chronc change in resting concentrations, chronic change in acute response to exercise, and receptor changes.
