used to protect internal organs?
musculoskeletal system
Homeostasis
maintenance of a stable internal environment
Negative Feedback
A primary mechanism of homeostasis
a process in which the body senses changes and activates
mechanism that negate or reverse it.
Positive Feedback
the body senses change and activates mechanism that accelerate
or increase that change (amplifies)
Receptor
a structure that detects change
, Control Center (integrating)
a mechanism that process the information; makes the decision
Effector
the cell organ that carries out the final corrective action;
"responder"
