homeostasis. the tendency of biological systems to maintain relatively constant conditions in the internal environment while continuously interacting with and adjusting to changes originating within or outside the system. See also balance and equilibrium. adj., adj homeostatÂ´ic.
Homeostasis. It is important that the bodyâs internal environment is controlled. For example, the amount of carbon dioxide in the bloodstream is carefully controlled. Maintaining a constant internal environment is called homeostasis. The nervous system and hormones are responsible for this. Here are some of the other internal conditions that are controlled: Blood sugar level. This is controlled to provide cells with a constant supply of energy. The blood sugar level is controlled by the release and storage of glucose, which is in turn controlled by a hormone called insulin. Body temperature. This is controlled to maintain the temperature at which enzymes work best, which is 37Â°C. 1  Body temperature is controlled by: 2  controlling blood flow to the skin. 3  sweating. 4  shivering.
