Endocrine System
- sends message as a hormone (adrenaline)
- its message is long lived
- the message travels slow
- the message travels through the blood
- the message is created by endocrine cells
Nervous System
- sends message in the form of electrochemical messages (Na+, K+)
- the message is short lived
- the message travels fast
- the message travels through neural passages (nueron)
- the message is created by nerve cells
- Control and coordination within a body depend on both the endocrine and nervous system.
