  1. Homeostasis refers to the body's need to reach and maintain a certain state of equilibrium. The term was first coined by a physiologist named Walter Cannon in 1926. More specifically, homeostasis is the body's tendency to monitor and maintain internal states, such as temperature and blood sugar, at fairly constant and stable levels
  2. Homeostasis Definition. Homeostasis is the ability of living systems to maintain a steady and uniform internal environment to allow the normal functioning of the systems. It is the tendency to achieve equilibrium against various natural and environmental factors. Homeostasis results in a dynamic equilibrium, where continuous changes keep on.
  3. Homeostasis is the regulation of conditions in the body such as temperature, water content and carbon dioxide levels. Diabetes is a condition where the body cannot regulate its blood glucose levels
  4. Homeostasis, from the Greek words for same and steady, refers to any process that living things use to actively maintain fairly stable conditions necessary for survival
  5. Homeostasis is the ability to maintain a relatively stable internal state that persists despite changes in the world outside. All living organisms, from plants to puppies to people, must regulate.
  6. Homeostasis definition is - a relatively stable state of equilibrium or a tendency toward such a state between the different but interdependent elements or groups of elements of an organism, population, or group. How to use homeostasis in a sentence
  7. Introduction to Homeostasis. Homeostasis refers to the body's ability to maintain a stable internal environment (regulating hormones, body temp., water balance, etc.).

Maintaining a stable internal condition is crucial to any form of living thing.Different physiological strategies are employed to maintain the proper functioning of a system in spite of the external environment's dynamicity 1. Maintenance of Body Temperature. One of the most common examples of homeostasis is the regulation of body temperature. In humans, the normal range falls on 37 degrees Celsius or 98. 6 degrees Fahrenheit. In order to maintain this, the body controls temperature either by producing heat or releasing excess heat La homeostasis es necesaria debido a que nuestro cuerpo tiene unos límites bastante estrechos. En el caso de la temperatura, si no fuéramos capaces de regular nuestra temperatura corporal, seríamos totalmente vulnerables. Si estuviéramos en un lugar donde hiciera mucho calor, nuestro cuerpo sería incapaz de controlarlo
