    Jun 18, 2016 · In contrast to negative feedback loops, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state.

  2. Homeostasis and feedback loops (article) | Khan Academy

    So, negative feedback loops counteract or oppose a change, while positive feedback loops amplify it, meaning that the cycle is continued until the process is done.

  3. Physiological concept of positive and negative feedback

    Positive feedback increases a product, creating a chain effect. Negative feedback controls a process to prevent product accumulation, maintaining balance in our bodies.

  4. Feedback in living systems (video) | Khan Academy

    Feedback mechanisms can encourage (through positive feedback) or discourage (negative feedback) what is going on inside the organism.

  5. Feedback (practice) | Khan Academy

    Which of the following correctly describes how positive and negative feedback are different?

  6. Negative feedback loop examples (article) | Khan Academy

    The primary way that organisms maintain homeostasis is through negative feedback loops. These feedback loops counteract, or oppose, a change in the organism. In this article, we’ll cover …

  7. Positive feedback loop examples (article) | Khan Academy

    Positive feedback loops drive processes to completion Feedback loops are a critical part of homeostasis, which is the tendency of organisms to maintain relatively stable internal …

  8. Homeostasis (video) | Feedback | Khan Academy

    Homeostasis, or maintaining a steady body temperature, is achieved through feedback mechanisms. Exposure to extreme temperatures triggers physiological responses like …

  9. Body structure and homeostasis review (article) | Khan Academy

    In contrast to negative feedback loops, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state. The ripening of fruit is an …
