Medical Assistant Prep / Unit 2 MAS 030 short lesson, about 20 seconds
Homeostasis: Keeping the Inside Steady
Captions available
The idea
Survival depends on homeostasis: keeping internal conditions, such as temperature and chemistry, within a narrow range.
In practice
Vital signs are a window on homeostasis; a fever or racing pulse often shows the body working to restore balance, or failing to.
Where people slip
An unusual reading is a signal for the provider to interpret, not a diagnosis for you.
