If the water potential of blood increases above normal ⇒ it is detected by receptor (detector) in your body. ⇒ Body will respond by returning WP to normal level.
in homeostatic control ⇒ body reacts to bring about an opposite effect to the changes detected. if your system (body) is disturbed ⇒ disturbance sets in motion a sequence of events that tends to restore the system (your body) to its original state. ⇒ this is the Negative feedback process
There are organs or structures in body ⇒ that can detect changes in body condition. ⇒ these organs or structures are called receptors or sense organs. ⇒ any change from the normal condition is called the stimulus
Negative Feedback process
- Normal level or set point to be maintained
- a stimulus, which is a change in the internal environment
- a receptor that can detect stimulus and send signals to control centre
- corrective mechanism, which brings about the reverse (opposite) effect of the stimulus
Note
effectors are the stuff that bring about the opposite effect. so after they bring about opposite effect, the control centre sends feedback to effectors to reduce the opposite effect
Definition
Define Negative Feedback: Automatic; brings opposite effect to the change to restore norm #BiologyDefinitions
Receptors detect that the set point is reached, causing corrective mechanism to stop.
