It is not uncommon to find calcified areas in fibroid tumors of the uterus, and in any old chronically infected area. In all such conditions Nature's first call is on the normal body calcium, in the hope that it may be used as a defensive mechanism in the area where disease is going on. There is no question but that calcium is one of our greatest body needs, as the bony structures of the body are perhaps the greatest in bulk and weight next to the voluntary muscles. In order that physiological processes may be carried on in a normal, proper way, oxygen must be carried to each individual cell. The oxygen is carried to the cells of the body by a compound which is made up partly of iron.
Oxygen enters the lungs, penetrates the wall of the air cells, and enters the blood.
The iron containing hemoglobin exists in the red blood corpuscles and having combined with the oxygen, carries it to the cells, where oxidation takes place. Without iron, no metabolism and no oxidation would occur. The need for iron is constant, as much of the hemoglobin is being destroyed and excreted every day. In the life processes of the ordinary individual, around 3 percent of the red cells are being destroyed every day. This means that a certain definite amount of iron must be provided to make up for what is lost.
