Homeostasis Maintaining the internal state
within narrow limits even
during external change
How is homeostasis maintained? Autoregulation or extrinsic
regulation
Autoregulation occurs when the activity of a
cell/tissue/organ adjusts
automatically in response to
environmental change
Extrinsic regulation changes result from the
actions of the nervous or
endocrine system
General regulatory mechanisms consist of: Receptor, control center, and
effector
Negative feedback Response shuts off or
migrates to original stimulus
Positive feedback Response exaggerates
original stimulus
Metabolism sum of all chemical
reactions in cells (catabolic
+ anabolic reactions)
