ELIMINATION
The Body's Safety-First in Keeping Health
The body is made up of billions of little cells. These individual cells are in a state of perpetual activity. They exhaust, wear away, break down with work and rebuild on food and rest. Every process of life—the beat of the heart, the throb of the brain in thought, the digestion of food, the excretion of waste—all are due to the activity of groups of highly specialized individual cells.
Every cell uses up its own material and throws off poisonous by-products during activity. These by-products, or wastes, are very poisonous to the individual cell as well as to the entire organism. To get rid of this waste is one of the first duties of the system.
It is with the body, made up of its countless millions of individual cells, just as with a city and its myriad people: the sewage of the community must be collected and disposed of. The city forms its poisons which we call sewage and the body its poisons, which we call excreta (or carbonic acid, urea, uric acid, faeces, etc.) It is no more important for a city to gather up and get rid of its poisonous sewage than for the animal organism to collect and excrete its cell-waste. Hence, the importance of maintaining normal and constant elimination throughout the body.
Elimination is kept up by the alimentary tract, the kidneys, the skin, and the lungs.
These four are the great pipe-line sewerage systems so to speak, by which the body throws off its gaseous, liquid and solid poisons.
The lungs momentarily strain carbonic acid out of the blood and throw it out in the expired air. They likewise exhale other noxious matters from the system.
The alimentary tract throws off faeces, made up of the waste tissue from the whole system, especially the digestive organs, as well as indigestible and non-nutritious portions of the food.
