Homeostasis
Homeostasis
The process of maintaining stable internal conditions in the body, despite external changes.
Negative feedback loop
Negative feedback loop
A feedback loop that reverses a change in the body to maintain homeostasis.
Positive feedback loop
Positive feedback loop
A feedback loop that amplifies a change in the body, driving it further from homeostasis.
