THE NERVOUS SYSTEMAll organisms need to adjust their bodies to changing internal and external
environments (need a way of detecting change and responding to it)
Stimulus - a change in internal or external environment
Response - the change that takes place in the body of an organism
Sensitivity - the ability to recognise a stimulus and make a suitable
response
Receptor - the cell or organ that detects the stimulus
Effector - the part of the body that responds to the stimulus

, ENDOCRINE SYSTEM:
System responsible for slower, longer lasting responses eg. Growth/digestion
- collection of glands that produce hormones
