There can be little doubt that during periods of stress in the body the various organs cooperate in an effective way as far as possible to avert an impending debacle. Each is sacrificed according to the extent to which it can be spared. Hence Parsons5 remarks that an organism is not a collection of independently working organs but is a unified, correlated system in which the activities of each part work for the furtherance of the life of the whole. From this point of view one can readily appreciate why the brain and the heart are the structures that suffer least impoverishment when starvation depletes the bodily reserves; for they must remain active and alert until the end if the functions are to be successfully executed. Nevertheless there is such a manifestation as myocardial failure. It ought to be helpful to know on what it depends.
