1
Homeostasis
Homeostasis is maintained by negative feedback (stay by target) loops and positive feedback (go beyond target) loops
Receptors: Detect stimulus
Effector: Change
2
Feedback Loops
Regulation of a stable internal environment in our bodies.
Positive Feedback: Blood clotting, childbirth, digestion, nerve signals (End products of an action cause) (away from the target)
Negative Feedback: (sugar in blood) triggers insulin to be release to remove glucose from blood) (inhibit action from continuing) (stay by the target)

Homeostasis: Thermoregulation
Thermoregulation is a process that allows your body to maintain its core internal temperature
Heat can be exchanged between an animal and its environment through four mechanisms: radiation, evaporation, convection, and conduction
