moments even, life becomes extinct, and you are no longer an animate being. A strong heart, therefore, is if anything even more important than a strong stomach. But you must remember that the strength of the heart to a large extent depends upon the cooperation of a strong stomach, or at least upon the proper digestion of food. For the muscles and tissues of the heart, like those of all other organs of the body, are fed by the blood, which depends for its life-giving and life- sustaining qualities upon the food, which is first acted upon by the stomach and thus made available for use by the cell structures in all parts of the body. The heart is truly a wonderful organ, the one set of muscles which apparently never rest, but work on night and day, year after year, throughout our entire life.
Furthermore, the part played by the lungs in the maintenance of life and health cannot be underestimated. Impaired functioning of the lungs has an immediate and vital effect upon every other part of the body. It is through this channel that we secure the oxygen, without which the processes of life would terminate almost instantaneously. It is through this channel also that the elimination of carbonic acid gas is accomplished. Without the continuous and thorough elimination of carbonic acid our tissues would become choked up and poisoned in such a way that all cell activity and bodily function would come to an abrupt end. If the lungs are sound and healthy in every respect the supply of oxygen is abundant, and the elimination of carbonic acid, which may be regarded as the "smoke" of the human system, is carried on perfectly. Breathing is only one of the various functions that must be continuously carried on, but it is of such importance as to require special attention in building vitality.
In the work of eliminating impurities and keeping the system clean the kidneys are to be classed with the lungs, although they have to do with poisonous wastes of a different type. Insufficient functioning of the kidneys is not so immediately fatal as the failure of the lungs to do their work, but proper action of the kidneys is none the less important. If the poisons which are normally eradicated from the system in this way are allowed to remain or to accumulate, they poison the body as truly as any external toxic element that could be introduced. Insufficient activity of the kidneys leads to the accumulation of those poisons, bringing on convulsions of the most serious nature, and unless the condition is relieved there will be fatal results. The requirements of health, therefore, demand that the kidneys should be strong and active, and that their functional capacity should be maintained at the highest degree of efficiency.
In supplementing the work of the kidneys and the lungs, the excretory function of the skin is only secondary in importance. The skin has various functions. It is one of our chief organs of sense, the sense of touch being hardly second to those of sight and hearing. It is likewise a wonderful protective structure, and at the same time is a channel of elimination which cannot be ignored with impunity. To interfere with the eliminative function of the skin by absolutely clogging the pores for a period of several hours means death. One may say that we really breathe through the skin.
The importance of all these functions of elimination is vital. Pure blood depends upon the perfect and continuous excretion of the wastes formed in the body through the processes of life, and without keeping the blood pure in this manner the body rapidly becomes poisoned by its own waste products, with the result that health, vitality and even life are lost. Health is entirely a question of pure blood, and, while the blood depends first upon the building material supplied through the digestive system, it also depends equally as much upon functional activity in the matter of elimination.
The liver, which enjoys the distinction of being the largest organ in the body, is designed for the performance of a multiplicity of functions. It not only produces the bile, which has such an important part to play in the work of digestion, but it has a very important work in the changing of foods absorbed into such material as may be assimilated or used by the cells of the various tissues throughout the body. For instance, it is part of the function of the liver to bring about chemical changes in albuminous foods which make it possible for the tissues to assimilate these. It also has much to do with bringing about certain chemical changes in sugar or dextrose. Furthermore, the liver has an important function in connection with the excretion of
