positive feedback system
Positive feedback mechanisms amplify changes in a system, causing the variable to deviate further from its original value or range. This can lead to destabilization or self-reinforcing processes. Examples include childbirth contractions and forest fires.
A positive feedback loop can disrupt a system in homeostasis by amplifying an initial change away from the set point, leading to an escalation of the deviation. This can push the system further out of balance and prevent it from returning to its original state. In extreme cases, a positive feedback loop can result in system failure or collapse.
The positive feedback loop is terminated by the end of childbirth...
In a feedback amplifier, positive feedback produces an output that is in-phase with the input signal. This can lead to instability and oscillation in the amplifier circuit. Positive feedback can increase the gain but at the risk of introducing noise and distortion.
positive feedback system
If a change in the body causes more change in the same direction, the system is called positive feedback. This feedback loop amplifies the initial change and pushes the system further away from its original state.
The Negative feedback System & the Positive Feedback System are the two types of Homeostasis
Positive feedback causes bodily processes to continue; negative feedback causes bodily processes to start or stop only cost you being in my basement
when a woman's contractions speed up during labor is negative or positive feedback

In a positive feedback system, the output enhances or amplifies the input that started the process, causing a self-reinforcing loop. This means that an increase in the output leads to an increase in the input, continuing to drive the system further in the same direction.
A positive feedback mechanism is a system the responds to perturbation in the same direction as the perturbation. A positive feedback mechanism allow cells to adapt to changes in their environment rapidly and efficiently. Positive feedback allows cells to reach new levels of equilibrium corresponding to the stimulus in the environment

Negative feedback mechanisms work to maintain homeostasis by reversing a change in a physiological parameter, bringing it back to its set point. In contrast, positive feedback mechanisms amplify a change in a physiological parameter, leading to a continued deviation away from the set point until a specific endpoint or outcome is achieved.
Oxytocin in the process of giving birth. Oxytocin causes uterine contraction, which causes the baby to push up against the cervix, which causes more oxytocin to be released. And the cycle continues until the baby is born.
