nervous system should be regarded as the real center of life, but the 
function of the heart, the marvelous muscle-pump, is so vital and 
indispensable that the world is accustomed to thinking of it as the organ 
of first importance. And so it is. Should it cease its efforts for a few 
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
