Yes, defecating a form of positive feedback.
Rectal contraction at defecation is suggested to be maintained by positive anorectal feedback evoked by continuous passage of stool through the rectal neck. This feedback appears to be affected through an anorectal excitatory reflex (ARR), which produces rectal contraction upon stimulation of anal stretch receptors. Abortion of this reflex by anal anesthetization seems to result in failure of the rectum to contract and in excessive straining to achieve rectal evacuation. ARR thus is suggested to be a second defecation reflex necessary to continue defecation, whereas the rectoanal inhibitory reflex is the primary reflex.

Is child birth negative feedback?
the delivery of a baby is positive feedback if you have done it well. This is because people will tell you how you have done and they will tell you the positive and negative things about the process.
What is an example of positive feedback during sports?
a goal going in in football . the player watches the ball go in the net and that is seen as positive feedback Whats sort of answer is this???????????????? This answer means that by seeing the goal go in the player receives internal postivie feedback, they know what they have done is a ggod thing so they fell a sense achievement. This is positive feedback. Not external positive feedback like normal positive feedback, that is in the form of a compliment from a coach or something similar! hope this helps
Feedback is when the body reacts in the same direction as a stimulus. Negative Positive?
Feedback can be both negative and positive. Negative feedback occurs when the body's response counteracts the stimulus, helping to maintain homeostasis. Positive feedback amplifies the stimulus, leading to a larger response.
When the initial stimulus produces a response that reinforces the stimulus the mechanism is called?
positive feedback
Compare and contrast negative and positive feedback mechanisms and give some examples?
Negative feedback mechanisms work to maintain homeostasis by reversing a change in a system, while positive feedback mechanisms amplify and reinforce a change. An example of negative feedback is the regulation of body temperature – if body temperature rises, mechanisms kick in to lower it; whereas in positive feedback, childbirth contractions become stronger and more frequent to facilitate delivery.
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?
Positive feedback Positive feedback
How is a positive feedback stopped?
The positive feedback loop is terminated by the end of childbirth...
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
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.
What type of feedback is used in the phase shift oscillator circuit?
Positive feedback
What is the purpose of feelback how can you offer positive feedback?

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