Kiryat red and essential function of the oxygen-carrying O2 from the lungs to the tissues and carry carbon dioxide Co2 from the tissues to the lungs to get rid of the body and transporting food, hormones, salts and secretion from the cells and other Mananba parts of the body, is the main vector, otherwise it will not continue life ..

The estimated lifetime of red blood cells b (120) days, and contains a substance protein specialized for this purpose is the hemoglobin, consisting of hemoglobin from four molecules of Hem contain iron atoms in the case of reduction (virus, Ferrous Fe +2 Algelobin Globin), the part of the protein consisting of four chain amino acids Amino Acid Chains ..

The main source for the production of red blood cells is bone marrow (Bone Marrow), but in cases of severe anemia such as broken blood, liver, spleen begins to produce pellets in aid to the marrow, leading to inflation ..

The blood from 5-6% of normal body weight, and up the number of red blood cells to about 5 million cells per cubic millimeter ..

What is anemia??

Children age 6 months to 6 years: 11 g / 100 ml
Children age 6-14 years: of 12 g / 100 ml
Adult males: 13 g / 100 ml
Adult females: 12 g / 100 ml
Pregnant women: 11 g / 100 ml

As for the people who live above sea level, the values given to the hemoglobin concentration will be higher ..

The anemia food is defined as a state of the inability of the tissue component of red blood cells access to the natural concentration of hemoglobin (the hemoglobin) due to lack of supply to one or more of the essential nutrients that will separate to talk about it later, could worsen the situation of loss over most of the cells or cells red blood ..

Certain types of anemia food: ..

Of the most important types of anemia food in the world and the Arab world:.

Anemia due to iron deficiency (iron deficiency)

Chemists have found that iron is more stable metal did not reach far from science to discover the properties of iron metal in clothing and strength, flexibility, and the severity of bearing the pressure ..
The iron deficiency is the most common, followed by lack of folate and vitamin B 12 deficiency and copper and protein, which are rare in the Arab world, and have vitamin C deficiency reason behind the occurrence of anemia of newborn babies, and meet a number of reasons together to produce anemia, for example, food shortages, multiple causes ..

And functions ..:

It is necessary to Onzimat many, including catalase, which is important and necessary for the safety of the immune system and energy production ..

The human body contains of the 3-5 grams of iron .. Almost two thirds of the iron found in hemoglobin in red blood cells (2.5 - 3 grams) ..

Stores iron in the liver and muscle cells and retinal endothelial by 0.5 - 1.5 grams, and is two-thirds of the body Elvirtin (a compound of iron and protein) soluble in water and is available directly for the production of hemoglobin and a third in the form of Alimosideren (a compound of iron and protein) insoluble in water ..

Body needs to compensate for the lost day of iron as follows: ..

* A person loses of from 0.5 - 1 mg per day in the feces, sweat and urine.
* Women lose 30-40 ml of blood per month during the menstrual cycle and this is equivalent to approximately 0.5 - 0.7 milligrams of iron daily, and during growth in children 0.6 mg per day.
