PPT-Homeostasis

the physical process that maintains a stable internal environment example body temperature Endotherms animals that can generate amp regulate their own body heat Their body temperature. AP Biology. Homeostasis and the Environment. So far, we have looked at how homeostasis controls and regulates our bodies (removal of nitrogenous waste, immune system). . While these are good examples of homeostasis, they are at an organism or cellular level. . Homeostasis. Homeostasis is the maintenance of a . stable internal environment.. Homeostasis. Homeostasis represents a state of . DYNAMIC EQUILIBRIUM.. Homeostasis. Homeostasis represents a state of . The Human Body. An IRSC . L. ive Virtual Lesson. By: Diana Lenartiene, Ed. S. . 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.
