Homeostasis and its Mechanism
As mentioned earlier in the page homeostasis is the reletively stable conditions that the human body maintains to keep the internal environment of the body functioning healthily. This also allows cells for example the red blood cell function properly, to be able to carry oxygen around the body. There are several different homeostatic mechanisms that can occur in the body.
Homeostatic mechanisms all use a negative feedback in order to maintain the set point or the value. This enables the efficiency of the body to carry out tasks and activities. The negative feedback that these mechanisms use means that anytime change occurs in a system in the body, the negative feedback is able to automatically cause a correction mechanism to begin and further reverse the original change that might have occurred. This in turn takes the system back towards the normal set point in which the system usually operates. Therefore the size ofthe corrective mechanisms depends on the size of the initial change. The negative feedback system could be illustrated in the same way when it comes to electronic systems. For example when an oven gets too hot, the heating system is automatically turned off in order to avoid fires, which would be considered an extreme case. In the same way, the human body uses the negative feedback system as the central heating control of the body. This means that the biological systems of the body are able to cool down in order to keep the internal temperature at a normal value.
Therefore in a system where a negative feedback system controls the set level of the body, it can be recognized that the level is never perfectly maintained, instead it is in constant oscillation around the normal value that the human body is meant to be at. For a homeostatic system to be considered as efficient, it is required to be able to minimize the size of oscillation.
There are several different mechanisms the body goes through these include thermoregualtion, osmoregulation feedback loops, and many more.
