GENERAL HISTOLOGY

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: -There are two types of feedback in homeostatic systems: negative and positive feedback. Each type of feedback promotes a change in the homeostatic system relative to the set point, but they each do this differently.

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.

Detailed explanation-5: -Negative feedback occurs when a system’s output acts to reduce or dampen the processes that lead to the output of that system, resulting in less output. In general, negative feedback loops allow systems to self-stabilize. Negative feedback is a vital control mechanism for the body’s homeostasis.
