Disease

"Disease: a cells response to injury. Either the cell will adapt or die."

Disease can be defined as a cell's way (ability) of reacting to change. It is a set of responses of an organism, which is a collection of cells, to change. The human body lives within a static state, termed homeostasis which is maintained at a regular level to prevent fluctuations in molecules, signals and ionic/charge levels. Any change can lead to changes in the static state of a cell, and like in natural selection, cells like organisms in nature, begin to adapt by producing proteins and changing levels of proteins within them to be able to survive in this new envirnoment. If the cell is unable to adapt to the new stimulus or change, it will die. Cell death may occur through apoptosis or necrosis. The changes caused by the new stimulus or change in the environment can be reversible or irreversible.
