Verified step by step guidance

Understand the concept of feedback loops: Feedback loops are biological mechanisms whereby the body maintains homeostasis. They can be either negative or positive.

Define negative feedback: Negative feedback loops work to counteract changes in the body, bringing it back to a set point. This is the most common type of feedback loop in the human body.

Define positive feedback: Positive feedback loops amplify changes, moving the system away from its starting state. These are less common and usually occur in specific situations like childbirth.

Consider examples: Negative feedback examples include regulation of body temperature and blood glucose levels. Positive feedback examples include the release of oxytocin during childbirth.

Conclude which is more common: Based on the definitions and examples, negative feedback loops are more prevalent in maintaining homeostasis in the human body.
