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.

Cells, tissues, organs, and organ systems maintain relatively stable internal environments, even in the face of changing external environments. What is homeostasis?. Process that occurs in all living things. Cells Homeostasis Cells work together to maintain homeostasis . Cells have different functions. Homeostasis = stable environment in your body; balance Your body maintains its homeostasis even if outside conditions are changing. Function of the Cell Membrane:.
