Why is the human baby being born an example of positive feedback?

Back

Define homeostasis.

Back

The process by which living organisms maintain a stable internal environment.

Front

What is a feedback loop?

Back

A biological mechanism that regulates physiological processes.

Front

What is the role of receptors in feedback systems?

Back

Receptors detect changes in the environment and send signals to effectors.

Front

What is the difference between positive and negative feedback?

Back

Positive feedback amplifies changes, while negative feedback reduces changes.

Give an example of a negative feedback mechanism in the human body.

Back
