Iron Metabolism : Transportation and Storage, Absorption and Regulation, Daily loss of iron : USMLE
Iron metabolism is a vital process in the human body, ensuring that this essential mineral is efficiently absorbed, transported, stored, and regulated 🌟. Iron is absorbed in the duodenum and upper jejunum of the small intestine, primarily in its ferrous (Fe2+) form. Once absorbed, it binds to transferrin in the blood for safe transportation to various tissues 🚚. Iron storage occurs mainly in the liver, spleen, and bone marrow in the form of ferritin and hemosiderin, ready to be mobilized when the body needs it 🔒. The body meticulously regulates iron levels to prevent deficiency, leading to anemia, or excess, causing toxicity. Regulation involves the liver-produced hormone hepcidin, which inhibits iron absorption from the diet 🛑. Despite efficient recycling, a daily loss of iron occurs through shedding of epithelial cells, sweat, and other minor routes, necessitating a steady dietary intake 🥗. Understanding iron metabolism is crucial for medical professionals, especially when preparing for exams like the USMLE, to diagnose and treat disorders related to iron imbalance efficiently 📚.

Why is iron converted back to Fe3+, before entering the blood vessels ?

I have Hereditary Hemochromatosis. Iron overload.
