The liver also breaks up the worn-out red corpuscles putting them into condition to be eliminated in the bile.
It oxidizes and renders harmless poisonous substances absorbed in the food, such as fermented food products and alcohol.
The Muscles oxidize the fats and sugars liberating the latent heat and energy. They partly oxidize proteins which are further broken up in the liver.
The Nerves oxidize food materials stored in the nerve cells, providing nervous energy.
The Lungs absorb oxygen and throw off carbon dioxid, watery vapor, and some organic substances.
The Kidneys and the Skin excrete water, carbon dioxid, and nitrogenous waste.
The Blood carries the vital elements derived from the food to all the organs and tissues, keeping them alive and actively functioning. It also carries waste products to the skin, lungs, kidneys, and intestines for elimination.
FACTORS INFLUENCING DIGESTION
As before stated, it is not the food eaten, but that which the body digests and assimilates, or appropriates to its needs, which counts. Many factors influence such nourishment. The principal aids are a forceful circulation, the plentiful breathing of oxygen, and free elimination.
