Is considered the cause of most diseases

|
|
Is when the internal conditions of the body become more stable
|
Detailed explanation-1: -Many diseases are a result of homeostatic imbalance, an inability of the body to restore a functional, stable internal environment. Aging is a source of homeostatic imbalance as the control mechanisms of the feedback loops lose their efficiency, which can cause heart failure.
Detailed explanation-2: -Common problems such as confusion, irritability, aggression, anxiety, listlessness, delirium, increased heartbeat, low blood pressure, fast breathing, decreased urine output, constipation and falls can be a direct consequence of a homeostatic imbalance.
Detailed explanation-3: -Homeostatic imbalance is a fluctuation in the ability to maintain equilibrium and a constant environment within the body. For example, if a person is having a homeostatic imbalance they may not sweat properly. This would cause them to overheat which can lead to hyperthermia and heatstroke.
Detailed explanation-4: -Homeostasis is brought about by a natural resistance to change when already in optimal conditions, and equilibrium is maintained by many regulatory mechanisms: it is thought to be the central motivation for all organic action.
