Lastly‚ the effects of temperature‚ hormones‚ and ions will be understood. Epinephrine‚ pilocarpine‚ atropine and digitalis are the hormones used to modify the heart. Sodium‚ potassium and calcium are the ions used in this experiment. Methods In the Vessel Resistance section for the Cardiovascular Dynamics experiment‚ two

hormone secretion occurs when there is a disturbance in the hormone’s concentration and levels differentiate with stimulation. Example of acute hormone secretion would be the release of epinephrine in the body. For example‚ if a person is afraid of lightning and they are caught in a lightning storm the body release epinephrine in result of fear. Episodic hormone secretion is when hormones are distributed occurs when hormones are introduced into the body at regular times and absorptions. An example of
