Explain the difference between a positive feedback loop and a negative feedback loop in physiological processes. Provide an example of each.
A negative feedback loop reverses the original stimulus to return the body to homeostasis, while a positive feedback loop enhances changes and deviations caused by the original stimulus. An example of a negative feedback loop is body temperature regulation, and an example of a positive feedback loop is childbirth.
