Detailed explanation-1: -Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points. In contrast to negative feedback loops, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state.

Detailed explanation-2: -Open and Closed-Loop Feedback Mechanisms Homeostasis is often achieved in the body through the use of feedback loops that regulate the body’s internal circumstances.

Detailed explanation-3: -Positive feedback systems in living things usually happen in response to a physiological stressor, such as blood clotting or childbirth. Negative feedback systems in living things continuously regulate critical body processes including temperature, pH, and hormone regulation to maintain homeostasis.

Detailed explanation-4: -Homeostasis is maintained by negative feedback loops within the organism. In contrast, positive feedback loops push the organism further out of homeostasis, but may be necessary for life to occur.
