The statement you provided describes a **negative feedback loop** rather than a positive feedback loop. In a negative feedback loop, the body responds to a change (in this case, low blood sugar concentration) by initiating processes that correct that change (secreting hormones to increase blood sugar concentration).
In contrast, a positive feedback loop amplifies a response or increases the change in the same direction (for example, during childbirth, the release of oxytocin increases contractions, which leads to more oxytocin being released).
If you need clarification or additional information about feedback loops or any concept, feel free to ask!
