Hemostasis involves both positive and negative feedback mechanisms, but it can be primarily characterized as a positive feedback process. When a blood vessel is injured, platelets adhere to the site and release signaling molecules that attract more platelets, amplifying the response until a clot is formed. This cascade continues until the bleeding is effectively stopped, demonstrating the positive feedback nature of hemostasis. However, once the clot is formed, negative feedback mechanisms help regulate and eventually dissolve the clot to restore normal blood flow.

How is a positive feedback stopped?
The positive feedback loop is terminated by the end of childbirth...
In a feedback amplifier positive feedback produces an output that is?
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.

Which kind of feedback is used to reinforce correct behavior?
constructive feedback
What is type of feedback in which a given action promotes more of the same?
The type of feedback that promotes more of the same action is positive feedback. It occurs when the result or outcome of an action increases the likelihood of that action being repeated or continued. Positive feedback reinforces and encourages the behavior or action that produced it.
Is blood pressure negative or positive feedback?
Is the clotting of blood an example of positive or negative feedback?
What is the difference between Positive feedback and Regenerative feedback?
positive feedback is always benificial but regenerative feedback may or may not.
Is contractions during childbirth positive or negative feedback?
Positive feedback.
Definition of negative feedback and positive feedback?
A: Any feedback that contributes to the input is positive feedback any feedback that subtract from the input is negative feedback
Tends to magnify a process or increase its output?

A blood clot stimulating the formation of more blood clotting is an example of?
Postive feedback
What is a positive feedback mechanism?
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

Can we use positive feedback in amplifiers?
Yes because an amplifier with positive feedback is an oscillator.
