The biological definition of homeostasis is “the tendency of an organism or cell to regulate its internal environment and maintain equilibrium, usually by a system of feedback controls, so as to stabilize health and functioning”. Generally, the body is in homeostasis when it’s needs are met and it’s functioning properly.. 12.1. Learning Objectives. Define homeostasis. Explain the importance of homeostasis. Describe how control mechanisms work. Explain how control mechanisms are co-ordinated. Success Criteria. You can define homeostasis and suggest what things need to be maintained in the body.
