What is Homeostasis?
“Homeostasis is 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.” (Dictionary.com, ©2012)
Homeostasis is the maintenance of a constant internal environment in response to
a changing external environment. Hormones are made of proteins; they are
released by glands in to the blood stream where they reach target cells. a
specific hormone will fit a specific receptor protein and this brings about a
change in the cell (Science aid, ©2006-2012).
It becomes a control system in order to always bring the body back to a constant, equilibrium, for
example, something like temperature. If it gets too hot, the nervous system and
the endocrine system control the process of homeostasis via negative and
positive feedback system sending the right impulses and hormones to the right
cells in the body. A positive feedback loop is to amplify the change and
negative is the reaction to reverse the change of direction in a system. these
loops are a continuous process, meaning no starting or finishing point and its
response alters the original reaction Nerve impulses and hormone function acts
the same as having a chemical and physical environment for the cells in your
body and this process involves three parts in maintaining balance; the
receptors, the control centre and the effector (Homeostasis definition, updated
