Verified step by step guidance

Understand the concept of feedback loops: Feedback loops are mechanisms used by the body to maintain homeostasis. They can be categorized as positive feedback loops, negative feedback loops, oscillatory feedback loops, or feedforward loops.

Define negative feedback loops: Negative feedback loops are processes where the body detects a deviation from a set point (e.g., blood glucose levels) and initiates a response to counteract the change, bringing the system back to its stable state.

Relate negative feedback loops to blood glucose regulation: In the human body, blood glucose levels are regulated by hormones such as insulin and glucagon. When blood glucose levels rise, insulin is released to lower them, and when levels drop, glucagon is released to increase them. This is an example of a negative feedback loop.

Contrast negative feedback loops with other types: Positive feedback loops amplify changes rather than counteracting them (e.g., childbirth contractions). Oscillatory feedback loops involve rhythmic fluctuations, and feedforward loops anticipate changes rather than responding to them.

Conclude that the correct answer is negative feedback loop: Based on the definition and examples provided, negative feedback loops are responsible for maintaining stable blood glucose levels in the human body.
