Homeostasis: Homeostasis is the ability of an organism or system to maintain internal stability by adjusting its physiological processes according to changing external conditions.
Feedback Mechanism: A feedback mechanism is a cycle where information about changes from one part of a system is used by another part of that same system for regulation or control.
Negative Feedback Loop: This type of feedback loop occurs when a response is triggered that reverses or counteracts an initial change, maintaining stability.
