Iron metabolism refers to the processes by which the body absorbs, utilizes, and stores iron, an essential mineral for various biological functions. Iron is primarily absorbed in the small intestine and is crucial for the production of hemoglobin, which carries oxygen in the blood. The body regulates iron levels through absorption and storage mechanisms to prevent deficiency or overload. The liver plays a key role in iron metabolism by storing excess iron in the form of ferritin and releasing it as needed. Additionally, proteins like transferrin transport iron in the bloodstream to cells. Proper iron metabolism is vital for maintaining overall health and preventing conditions such as anemia or hemochromatosis.
