Title - positive and negative feedback systems

HOMEOSTASIS According to totora .......... Homeostasis bathroom be defined as the see to it in which the probosciss home(a) milieu remains constant, at heart physiological limits. Homeostasis is a dynamic condition as the bodys equilibrium evidence crowd out change over a assign range that is congruous with maintaining life. E.g., the level of glucose in the blood does not principlely illume below 70mg of glucose per 100ml of blood. Each body social structure helps to contribute to keep the internal environment within its normal limits. For example, if the level of blood glucose within the drops then the body compensates it by using fats stores as a reserve supply of glucose be mentally ills An important aspect of homeostasis is maintaining the volume and root of body mentally ill. The fluid within cells is called intracellular fluid (ICF). The fluid international the body cell is called extracelluar fluid (extracellular fluid). Dissolved in the ICF and ECF are substances required to maintain life such(prenominal) as O2, nutrients, proteins and electrally aerated ions. Bernard predicted - the proper functioning of the body depends on precise regulating of the composition of the surrounding fluids of cells, known as interstitial fluid (internal environment). The composition of interstitial fluid changes as substances move in and out of the cell. For example, there is an re-sentencing of materials crossways the capillary walls. This exchange of movement in both directions provides the capillary with much needed ions such as glucose and O2 to tissue cells and removes wastes such as carbonic acid gas from interstitial fluid. Control of homeostasis Homeostasis in the body is continually universe disrupted. The disruption may come from the external environment such as the lack of O2 or the lack of heat. In nearly cases the disruption of homeostasis is mild and temporary and the body cells can reestablish the internal environment.
