Multiple Choice

Which statement is true regarding negative feedback loops in the human body?

Negative feedback loops are primarily involved in processes like childbirth and blood clotting.

Negative feedback loops are less common than positive feedback loops in the human body.

Negative feedback loops amplify changes and move the system away from its set point.

Negative feedback loops work to restore the system to its set point by counteracting changes.

Verified step by step guidance

Understand the concept of feedback loops: Feedback loops are mechanisms that help maintain homeostasis in the body by regulating physiological processes.

Differentiate between negative and positive feedback loops: Negative feedback loops counteract changes to bring the system back to its set point, while positive feedback loops amplify changes, moving the system away from its set point.

Identify examples of negative feedback loops: Common examples include the regulation of body temperature, blood glucose levels, and blood pressure, where the body works to restore balance.

Recognize the role of negative feedback loops: They are more common than positive feedback loops in the human body and are crucial for maintaining stability and homeostasis.

Conclude with the correct statement: Negative feedback loops work to restore the system to its set point by counteracting changes, ensuring the body remains in a balanced state.
