Basic bodily functions such as heart rate and breathing may be stimulated or slowed under neural control. Learn about the homeostasis of glucose and how hormones control blood sugar levels to prevent diabetes. homeostasis of the skeletal muscles by generating heat to warm you up. This collective volume contains the contributions to the Research Topic “Homeostasis and Allostasis of Thyroid Function”, which was originally published by the journal Frontiers in Endocrinology. The green portion of the feedback loop represents the process for lowering blood glucose levels while the blue portion of the feedback loop represents the process for raising blood glucose levels. Homeostasis is essential for life as without it humans would have to live within very specific conditions- we would never be able to survive in colder climates or hot desert without mechanisms to regulate our temperature. Homeostasis refers to the ability of an organism to maintain the internal environment of the body within limits that allow it to survive. The idea of homeostasis or maintenance of balance in the body started back in ancient Greece. In contrast, positive feedback loops push the organism further out of homeostasis, but may be necessary for life to occur. Learn how kidney and metabolic disease affect kidney function.
