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: -Also known as an inhibitory loop, a negative feedback loop allows the body to regulate itself. The process starts when there is an increase in output from a body system, which results in higher levels of certain proteins or hormones. This stops (inhibits or reverses) future production by the system.

Detailed explanation-3: -Negative feedback loops are used to maintain homeostasis and achieve the set point within a system. Negative feedback loops are characterized by their ability to either increase or decrease a stimulus, inhibiting the ability of the stimulus to continue as it did prior to sensing of the receptor.

Detailed explanation-4: -Examples of processes that utilise negative feedback loops include homeostatic systems, such as: Thermoregulation (if body temperature changes, mechanisms are induced to restore normal levels) Blood sugar regulation (insulin lowers blood glucose when levels are high; glucagon raises blood glucose when levels are low)
