ANATOMY

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 mechanisms; these are positive and negative feedback mechanisms. Figure 1: Positive Feedback Homeostasis, Negative Feedback Homeostasis.

Detailed explanation-3: -Positive feedback occurs to increase the change or output: the result of a reaction is amplified to make it occur more quickly. Negative feedback occurs to reduce the change or output: the result of a reaction is reduced to bring the system back to a stable state.

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.
