Answer:
The endocrine system, compared to the nervous system, is much slower.
The nervous system controls all the processes considered "secondary", since it is the one that captures the stimuli and transforms them into signals that will later be read in the different secretory organs, muscles, etc.
For there to be an endrocrine signal, there must first have been an electrical (nervous) signal that initiated it. Then there will be a secretory response, which will activate some receptor in the white tissues and initiate some response.
As you can see in order to arrive at an endocrine system response, it was first necessary to go through several previous steps.
