S. Each of the following observations were made in a lab rat after a specific gland or organ (or part of one) was removed. State what was removed in each case (be as specific as possible!) and briefly explain why the observed effect took place. NOTE: Assume the endocrine system of a rat works the same as that of a human. Observation What Was Explanation Removed? TSH levels in the blood increase significantly A stressful stimulus (a siren) caused an increase in heart rate but did not result in the increased breakdown of protein in muscle Blood levels of T3, T4, Cortisol, Growth Hormone all decreased drastically but levels of epinephrine and norepinephrine did not change.
