säätelymekanismia
Säätelymekanismi refers to a system or process that controls and maintains a stable internal environment within an organism or a complex system, despite external changes. This principle is fundamental in biology, where it explains how living things maintain homeostasis, a state of dynamic equilibrium. For example, the human body regulates its temperature, blood sugar levels, and pH through various feedback loops. When a factor deviates from its ideal set point, a detector identifies the change, and a control center initiates a response to bring the factor back to normal. This response is often mediated by effectors.
Negative feedback is the most common type of regulatory mechanism. In this system, the response counteracts
Beyond biology, the concept of säätelymekanismi is also applicable to engineering, economics, and social systems, where
