The Endocrine System
Captions available
The idea
The endocrine system is a network of glands that release hormones into the bloodstream to regulate bodily processes.
In practice
A hormone released into the blood reaches tissue throughout the body over seconds to minutes.
Where people slip
Hormones are slower and broader than neurotransmitters. Both are chemical messengers; only one has a target address.
