homeostasis Definition
the tendency of a system, especially the physiological system of higher animals, to maintain internal stability, owing to the coordinated response of its parts to any situation or stimulus that would tend to disturb its normal condition or function..

Phrases with homeostasis
a feedback loop in which the output signal increases the input signal, leading to an amplification of the original signal
Example
During childbirth, the positive feedback loop of uterine contractions leads to the release of oxytocin, which further stimulates contractions.
a feedback loop in which the output signal reduces the input signal, leading to a stabilization of the original signal
Example
The regulation of blood sugar levels by insulin is an example of a negative feedback loop.
allostasis
the process of achieving stability through change, often at a cost to the organism
Example
Chronic stress can lead to allostatic load, which can have negative effects on health.
Origins of homeostasis
from Greek 'hómoios' meaning 'similar' and 'stásis' meaning 'standing still'
Summary: homeostasis in Brief
Homeostasis [ˌhoʊ.mi.oʊˈsteɪ.sɪs] refers to the tendency of a system, especially the physiological system of higher animals, to maintain internal stability. It is achieved through coordinated responses of the system's parts to stimuli that would otherwise disrupt normal functioning. Examples of homeostasis include the regulation of body temperature and blood sugar levels. Positive and negative feedback loops are mechanisms that contribute to homeostasis.
