Homeostasis is the process through which living organism maintains a steady balance in the internal and external conditions of their bodies. Through the maintenance, the body system of living organism reach a steady state of equilibrium for a normal functioning of the body and therefore the body is able to maintain a balanced temperature and body fluids, the condition of homeostasis is normally brought up by a natural resistance to abrupt changes in environmental conditions, and therefore the equilibrium in the body is brought up by regulatory mechanism in the body (Aschner, 2015). This paper aims at expounding more on the process of homeostasis and how the process is used in the maintenance of conditions of life within the body.
To start with, the body is able to maintain its normal internal conditions through the help of homeostasis, to maintain this process; the body is required to make a continuous monitoring of the internal conditions, internal conditions such as body temperature, blood pressure to amounts of nutrients in the body. In order to maintain body conditions, control centers in the brain play a major role in regulating physiological activities therefore keeping body condition under normal circumstances. Through the process, any deviation from normal conditions of the body is resisted and normal conditions restored, through a process referred to as feedback loop.

A feedback loop can either be positive or negative, the main difference between the two being response to change, in which a positive feedback loop increases change while negative feedback loop makes a reduction in the change. Negative feedback therefore results in fewer products such as less salt in the system, less pressure, while positive feedback acts by moving away from the target, negative on the other hand reacts by moving towards the target for example the control of blood sugar levels in the body is an example of a negative feedback loop (Moroishi, 2015). Since the body system works most of the time in reversing the direction of change, negative feedbacks are mostly used to keep conditions constant.
