A mnemonic for the organ systems: Integumentary, skeletal, nervous, muscular, endocrine, cardiovascular, lymphatic, respiratory, digestive, urinary, reproductive
The existence of a stable internal environment
Occurs when a cell, tissue, organ or organ system adjusts its activities automatically in response to some environmental change
Extrinsic regulation
Caused by the activities of the nervous system or endocrine system
In homeostasis, the part that is sensitive to a particular stimulus
In homeostasis, responds to the commands given by the control center
Control center
In homeostasis, the part that receives and processes the information and then sends out commands
Negative feedback
A corrective mechanism involving an action that directly opposes a variation from normal limits
Positive feedback
An initial stimulus that produces a response that exaggerates or enhances the change in the original conditions
Positive feedback loop
An escalating cycle which does not stop without intervention
Dynamic equilibrium
The term for equilibrium that is maintained by constant action
State of equilibrium
This exists when opposing processes or forces are in balance
