Why homeostasis is important in organisms

Maintenance of Breathing Patterns 7. Regulation of Light Entry in Eyes 9. What is Homeostasis? By definition, homeostasis refers to the characteristic of a system that maintains the balance and stability between the internal and external environment. Maintenance of Body Temperature. Maintenance of Glucose Level. Protection From infection. Maintenance of Blood Pressure. Maintenance of Fluid Volume.

Maintenance of Breathing Patterns. Regulation of Light Entry in Eyes. Stable Population in An Ecosystem. Importance of Homeostasis. In the human body, chemicals like Oxygen O 2 , Carbon dioxide CO 2 and digested food enter and exit the cells using the concept called diffusion and osmosis.

For this process to function properly, homeostasis helps our body to keep both water and salt balance level.

Enzymes in the cell help in the speedy chemical reactions to order to keep the cells alive but these enzymes need to be in an optimal temperature to function properly. These mechanisms vary depending on the individual and may either be positive or negative feedback.

This alternate model of homeostasis, known as allostasis, implies that the ideal set point for a particular variable can shift in response to transient environmental changes, according to a article in Psychological Review.

The point may shift under the influence of circadian rhythms, menstrual cycles or daily fluctuations in body temperature. Set points may also change in response to physiological phenomena, like fever, or to compensate for multiple homeostatic processes taking place at the same time, according to a review in Advances in Physiology Education. For example, in anticipation of a meal, the body secretes extra insulin, ghrelin and other hormones, according to a review in Appetite.

This preemptive measure readies the body for the incoming flood of calories , rather than wrestling to control blood sugar and energy stores in its wake. The ability to shift set points allows animals to adapt to short-term stressors, but they may fail in the face of long-term challenges, such as climate change.

But they're not designed to last for long. Homeostatic systems may have primarily evolved to help organisms maintain optimal function in different environments and situations. The th eory posits that homeostasis makes it easier for organisms to extract important information from the environment and shuttle signals between body parts. Regardless of its evolutionary purpose, homeostasis has shaped research in the life sciences for nearly a century.

Though mostly discussed in the context of animal physiology, homeostatic processes also enable plants to manage energy stores, nourish cells and respond to environmental challenges. Beyond biology, the social sciences, cybernetics, computer science and engineering all use homeostasis as a framework to understand how people and machines maintain stability despite disruptions.

Many diseases are the result of the failure of one or more homeostats. Malfunction of a homeostat causes severe diseases , which can be fatal if not treated. For example type I diabetes mellitus, occurs when the blood glucose homeostat ceases to function because the beta cells of the pancreatic islets are destroyed.
