Even though conditions in the external environment may vary widely, most organisms must keep internal conditions such as temperature and water content fairly constant to survive.
<h3>What is homeostasis?</h3>
The tendency to maintain a stable, relatively constant internal environment is called homeostasis. The body maintains homeostasis for many factors in addition to temperature. For instance, the concentration of various ions in your blood must be kept steady, along with pH and the concentration of glucose. If these values get too high or low, you can end up getting very sick.
<h3>Homeostasis features:</h3>
- Homeostasis is the tendency to resist change in order to maintain a stable, relatively constant internal environment.
- Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points.
- In contrast to negative feedback loops, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state.
