Homeostasis Is a Central Theme In, Animal Physiology

Homeostasis is the name given to the process that allows optimum conditions to be regulated in the body. This regulation of the internal environment must be independent of external environmental constraints. In humans this process is controlled by almost all of the bodily systems but mainly by the endocrine, respiratory and renal systems. Homeostasis therefore allows an organism to live in habitats that are not ideally suited to the internal environment, because, only in favourable conditions will the organism thrive. This allows the organism to in an environment not best suited to it's internal functioning but in conditions which may be favourable for foraging etc. a prime example are fish, a fresh water fish lives in an environment which in definition is more dilute than within it's internal environment, sea water fish on the other hand live in a environment where its surroundings are more alkali than its internal environment.

The need for homeostasis can be "traced" to the cellular level, as cells interact with their immediate environment (either via cellular communication, signal proteins, expulsion of ion, and uptake of ions). It is this communication, which ultimately
