Maintenance of Life (part 2) Homeostasis

In a negative feedback mechanism, a deviation from the set point is corrected and the correction reduces the action of the

effectors.

The internal environment of the body consists of the

fluid that surrounds our cells, extracellular fluid and the cells themselves.

Effectors cause responses that alter conditions in the

internal environment.

Homeostasis is the body's maintenance of a stable

internal environment.

Receptors provide information about specific conditions in the

internal environment.

Control centers function to decide what a

particular value should be.

The three components of a homeostatic mechanism are

receptors, a control center, and effectors.

Homeostatic mechanisms are

self-regulating mechanisms that maintain homeostasis.
