Document Summary
The animal is separated using this black box from the external environment. Integument: boundary between the animal and its environment. Intracellular fluid (icf): fluid found within the cells, the composition is the most important. Where metabolism takes place all metabolic reaction take place here. Change in composition can have disastrous effect of enzymes that are doing the reactions. Water moving either into or water moving out to the. Net movement of water might concentrate or dilute the fluids, effect concentrations of solutes and therefore have negative affect since they were adapted to work at a particular type of environment. We have to make sure that water moves in and out and regular rates and make sure there is no net movement so we don"t establish a gradient and try to match the ecf with the icf. Only problem is that the ecf would not be the same as the external environment.
