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.

Are contractions in the uterus a process regulated by negative or positive feedback?
Uterine contractions are one of the few physiologic process regulated by positive feedback.
Positive feedback differs from negative feedback in that?
Most of the mechanisms in our body are regulated by negative feedback inhibition. In this type of process, the end product shuts off or reduces the intensity of the original stimulus. Production of certain hormones when mother is giving birth to a child is regulated by positive feedback inhibition. In this type of process, response leads to an even greater response.
Is blood regulated by negative or positive feedback?
negative feedback via baroreceptors in the carotid artery and aortic arch
What feedback continually enhances the output so that the regulated variable continues to be moved in the direction of the initial change?
That is called positive feedback.
Is blood pressure regulated by positive or negative feedback?
Aldosterone is both responsible for absorption of sodium and excretion of potassium. If it is regulated by the level of potassium in blood, then we have negative feedback as high levels of aldosterone causes a decrease in potassium level in blood. If it is regulated by the level of sodium in blood, the story is just the opposite and we have positive feedback. -my own conclusion from several researches-
Does the endocrine system often run on negative feed back?
Endocrine system usually uses the negative feed back mechanism. So suppose when thyroid stimulating hormone is released, then thyroid hormones are released. They reduce the secretion of thyroid stimulating hormone. This is how the secretions of the hormones is regulated. In positive feed back mechanism, the level of both the hormones will raise and will create lot of problems.
What are the hormonal responses and describe them?
The hormonal responses are basically responses or reactions given by the hormones. This response is triggered by either negative or positive feedback mechanism. When the hormone level is too low, the gland (usually endocrine) releases the hormones into the bloodstreams where it travels until it reaches the target organ. When there are too much hormones, the gland is triggered to stop the release of hormones. This mechanism of maintaining the balance without giving excess amount of hormone is known as negative feedback. In a positive feedback, the gland is triggered to release more hormones when excess amount of hormones is present.
How might a person exhibit positive feedback communication?
Positive feedback increases the original stimulus. An example is labor contractions. The initial contraction signals the body to release hormones that increase the frequency and intensity of subsequent contractions.
Is thermoregulation in humans regulated through positive or negative feedback systems?
Thermoregulation relies on negative feedback. Negative feedback works to return a system to homeostasis by reducing a stimulus, such as a change in temperature. By contrast, positive feedback systems amplify or speed up a response.
Is blood pressure negative or positive feedback?
Is the clotting of blood an example of positive or negative feedback?
Oxygen loading a positive of negative feedback process?
oxygen loading is a positive feedback response
What is the difference between Positive feedback and Regenerative feedback?
positive feedback is always benificial but regenerative feedback may or may not.
