Verified step by step guidance

Understand the concept of feedback loops: Feedback loops are mechanisms that help maintain homeostasis in the body. They can be either negative or positive.

Define negative feedback loop: A negative feedback loop is a process that counteracts a change in a physiological variable, bringing it back to a set point or normal range.

Identify examples of negative feedback: Negative feedback loops are common in the regulation of various physiological processes, such as temperature regulation, blood pressure control, and blood glucose levels.

Examine the role of insulin in blood glucose regulation: Insulin is a hormone that lowers blood glucose levels by facilitating the uptake of glucose into cells, thus counteracting high blood sugar levels.

Conclude why blood glucose regulation by insulin is a negative feedback loop: When blood glucose levels rise, insulin is released to decrease the levels, demonstrating a negative feedback mechanism that restores balance.
