HOMEOSTASIS
the ability to maintain a relatively
stable internal environment in an ever-changing
outside world
Homeostasis
The body is in a dynamic
state of equilibrium
The internal environment
interact to
maintain homeostasis
Chemical, thermal, and neural factors
Produces
change
in variable
Stimulus
Information
sent along
afferent
pathway to
Input
Information sent
along efferent
pathway
Output
Response of effector feeds back to influence magnitude of stimulus and returns variable to
