This is the collection of <font color=#ff0000>#$SystemConditions</font> which are dysfunctional for the system they affect. An dysfunctional condition is one which impairs the functioning of the system. For example, the function of an artery is to allow blood to flow to a part of the body, so that a blockage of the artery will constitute an abnormal condition of the artery to the extent that it reduces the flow of blood to that part of the body.
