Verified step by step guidance

Understand the concept of homeostasis: Homeostasis refers to the body's ability to maintain a stable internal environment despite changes in external conditions.

Identify the types of feedback loops: Feedback loops are mechanisms that help regulate physiological processes. The main types are negative feedback loops and positive feedback loops.

Define negative feedback loop: A negative feedback loop is a process where the body responds to a change by initiating responses that counteract or reduce the change, thus maintaining equilibrium.

Explain how negative feedback loops maintain homeostasis: Negative feedback loops help maintain homeostasis by reversing deviations from a set point. For example, if body temperature rises, mechanisms are activated to cool the body down.

Contrast with positive feedback loops: Positive feedback loops amplify changes and are less common in maintaining homeostasis. They are typically involved in processes that need a rapid completion, such as childbirth.
