Internal definition is - existing or situated within the limits or surface of something: such as. The purpose of homeostasis is to provide a consistent internal environment for set processes to occur. Negative feedback applies to electronic circuits and central heating systems as well as to biological systems. Biofeedback is the process of gaining greater awareness of many physiological functions of one's own body, commercially by using electronic or other instruments, and with a goal of being able to manipulate the body's systems at will. Feedback loops are important because they allow living organisms to maintain homeostasis. In computer science, a feedback loop refers to an endless loop of instructions that can be given to a computer that has no final step.
