*********************** ARTICLE START ***********************
Anemia translates as lack of blood. While it results from a number of underlying causes, it is most commonly associated with low levels of iron carried by molecules in the blood called hemoglobin, which comprises a significant fraction of the total volume of each red blood cell. In fact, iron is an elemental substance so essential in the human body that tissues and organs deprived of iron will not sustain damage for long periods of time, resulting in the death of the individual sooner than the complete depletion of iron.
Sixty to Seventy percent of iron present in the human body is contained in the blood, where it allows hemoglobin to play the indispensable role of carrying around oxygen for use by tissues and organs. Every day we lose a steady portion of the iron reserves in the body by way of the sweat glands and, in women, during menstrual periods. With that, whatever is left gets transferred to the red blood cells.
Intake of iron does not mean absorption inasmuch as the amount that ultimately gets digested by the intestinal walls is relatively low. Depending on the individual�s iron levels, the amount that is digested are either stored in the intestinal linings or transported to the rest of the body. Free iron at high levels damages cells in the liver, heart, and other organs, the reason why the body regulates each step in its digestion. Healthy concentrations of iron in the body signal the digestive tract to dispose of much of the iron stores in the intestinal linings together with other waste products, what is left is absorbed.
One common factor of most cases of anemia is the decrease in the amount of hemoglobin in the blood, and all individuals with iron deficiency suffer from this condition. How healthy red blood cells are is determined by the amount of hemoglobin it contains, the red color of the blood being produced by protein molecules that contain hemoglobin. The manufacture of red blood cells occurs in the bone marrow, and a significant amount of iron is stored therein. At times when the amount of iron is insufficient, the bone marrow creates fewer red blood cells, consequently leading to anemia.
How is iron an important composition of the blood? Red blood cells perform their function in the circulatory system only until around a hundred days. The life of red blood cells begins in the bone marrow, which replaces dysfunctional red blood cells in the bloodstream at any given time. The principal task of red blood cells is to pick up oxygen from the lungs and deliver it to the rest of the body. The capacity of each red blood cell to carry a certain amount of oxygen is directly governed by the amount of hemoglobin it contains. The higher the amounts of hemoglobin, the more efficient red blood cells become. The lower the levels of iron in the body, the lower the amounts of hemoglobin are contained in red blood cells.
Iron comes in convenient capsule or tablet supplement form at your local or internet vitamin store. Always choose name brands like Solaray or Source Naturals to ensure quality and purity of the supplement you buy.
