Positive feedback.
What else can I help you with?
The increasing labor contractions of childbirth are an example of?
positive feedback
What is a feed Back?
It depends on whether it is positive or negative feedback. Most biological organisms exhibit both negative and positive feedback, including humans. An example of positive feedback is contractions during childbirth. Negative feedback is blood sugar regulation based upon the release of insulin into the bloodstream at necessary times.

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.
Describing what is feedback system and differentiating between positive and negative feedback?
when a woman's contractions speed up during labor is negative or 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.
The increasingly forceful labor contractions during childbirth are an example of?
The increasingly forceful labor contractions during childbirth are an example of the body's natural physiological response to help facilitate the delivery of the baby. These contractions serve to push the baby through the birth canal and out of the mother's body.
What is the difference between positive and negative feedback loops?
Positive feedback loops amplify changes or effects, leading to an increase in the output or a runaway process, such as during childbirth when contractions intensify. In contrast, negative feedback loops counteract changes, promoting stability by reducing the output or returning a system to its set point, like how the body regulates temperature. Essentially, positive feedback drives growth or escalation, while negative feedback fosters balance and homeostasis.
Is Oxytocin release a positive or negative feedback control mechanism?
Oxytocin release is a positive feedback control mechanism. This means that an initial stimulus triggers the release of oxytocin, which then promotes further release of oxytocin, amplifying the response until a specific outcome is achieved, such as uterine contractions during childbirth.
What is the main difference between the way negative feedback and positive feedback loops regulate change in the body?
Negative feedback loops regulate change in the body by reversing a deviation from a set point, helping to maintain homeostasis. For example, when body temperature rises, mechanisms like sweating are activated to cool it down. In contrast, positive feedback loops amplify a response until a specific outcome is achieved, such as the release of oxytocin during childbirth, which intensifies contractions. Thus, negative feedback stabilizes systems, while positive feedback drives them toward a particular goal.
What is the difference between positive and negative feed back for homeostasis?
Positive feedback amplifies a process or increase its output, moving the system away from its starting condition, such as during childbirth when contractions intensify. In contrast, negative feedback works to counteract changes, restoring the system to its set point, like the regulation of body temperature. While positive feedback can lead to a significant change, negative feedback is essential for maintaining stability and balance in biological systems. Both mechanisms are crucial for homeostasis but serve opposite functions.
How is a positive feedback stopped?
The positive feedback loop is terminated by the end of childbirth...
