What is the difference between haemoglobin and hemoglobin

Iron also is needed for proper immune function. About 25 percent of the iron in the body is stored as ferritin, found in cells and circulates in the blood. The average adult male has about 1, mg of stored iron enough for about three years , whereas women on average have only about mg enough for about six months.

When iron intake is chronically low, stores can become depleted, decreasing hemoglobin levels. When iron stores are exhausted, the condition is called iron depletion. Further decreases may be called iron-deficient erythropoiesis and still further decreases produce iron deficiency anemia. Blood loss is the most common cause of iron deficiency.

In men and postmenopausal women, iron deficiency is almost always the result of gastrointestinal blood loss. In menstruating women, genitourinary blood loss often accounts for increased iron requirements. Oral contraceptives tend to decrease menstrual blood loss, whereas intrauterine devices tend to increase menstrual bleeding. Other causes of genitourinary bleeding and respiratory tract bleeding also increase iron requirements.

For blood donors, each donation results in the loss of to mg of iron. During periods of growth in infancy, childhood and adolescence, iron requirements may outstrip the supply of iron from diet and stores. Iron loss from tissue growth during pregnancy and from bleeding during delivery and post partum averages mg. Breastfeeding increases iron requirements by about 0. Your "iron level" is checked before each blood donation to determine if it is safe for you to give blood.

Iron is not made in the body and must be absorbed from what you eat. The adult minimum daily requirement of iron is 1. Only about 10 to 30 percent of the iron you consume is absorbed and used by the body. The daily requirement of iron can be achieved by taking iron supplements.

The main function of the red cell blood cell is the transportation of nutrients and oxygen to the cells and the removal of waste products and carbon dioxide; a process of which the hemoglobin is an intricate part of. The white blood cell helps fight off infections and heal the body. The platelets help the blood to clot.

The plasma helps in the transportation of these cells, as well as the transportation of various dissolved proteins, glucose, clotting factors, antibodies, mineral ions, hormones and carbon dioxide.

In addition to this, blood also helps regulate temperature, pH balance, and water balance. The name haemoglobin or hemoglobin comes from the fact that this protein consists of haem and the protein globin. Each molecule of hemoglobin is made up of four heme molecules, each of which is surrounded by a globin chain, for a total of four globin chains in the molecule.

Each of the four iron atoms go into the center of each of the four heme molecules. The primary function of haemoglobin is so carry and transport oxygen from the lungs to the cells of the body. The oxygen molecule gets picked up by the heme in the haemoglobin, which combines reversibly with it. The haemoglobin then travels from the lungs to various parts of the body, when it reaches a cell it releases the oxygen and then picks up the carbon dioxide to be released into the lungs.

Haemoglobin also carries the regulatory molecule nitric oxide to the cells and releases it at the same time as the oxygen. As transportation of oxygen is one of the main tasks of blood, haemoglobin is a very important aspect of the red blood cells.

There are millions of haemoglobin molecules present in each red blood cell, and there are millions of red blood cells present in the blood. There are many people out there that suffer from low hemoglobin. There are various causes for low hemoglobin such as iron deficiency, vitamin C deficiency, or folic acid deficiency. Low hemoglobin is a serious condition because hemoglobin is directly responsible for the transportation of oxygen from the lungs to the rest of the cells in the body.

Haemoglobin or hemoglobin is an iron containing protein in the red blood cell that helps carry oxygen from the lungs to the rest of the cells in the body. Difference between Haemoglobin and Hemoglobin.
