Homeostasis
The regulation of the
internal
conditions of a cell or organism to maintain optimum conditions for function in response to
internal
and external changes
View source
Enzymes and cells require very
stable
conditions in order to work
View source
The body has systems in place to keep the
internal conditions
optimum for the cells to
function
View source
Internal conditions maintained by homeostasis
Blood glucose
concentration
Body temperature
Water
levels

Automatic control system
Involves the
nervous
system or
hormones
View source
Automatic control system
1.
Receptor
cells detect changes in the environment (
stimulus
)
2.
Receptor
cells pass information to a
Coordination
Center
3. Coordination Center
receives
and
processes
the information
4. Coordination Center sends instructions to the
effector
5.
Effector
(muscle or gland) carries out the
response
