Slide 8 - Tekstslide

Hormones
= regulatory substances that control processes in the body
  • They do that by giving signals to organs (messengers)
  • Produced by hormone glands from the endocrine system
  • Transported by the circulatory system to get them where they need to be
  • Effect can have a duration of hours up until months/years
Dutch for glands = klieren
Messengers
Hormones are messengers. However, that was the task of the nervous system, right? The difference: the nervous system is for the fast messages (to help you feel and move), the hormones are for the slower messages (to help you grow and change).
