  2. Human iron metabolism - Wikipedia

    en.wikipedia.org/wiki/Human_iron_metabolism

    Iron deficiency first affects the storage of iron in the body, and depletion of these stores is thought to be relatively asymptomatic, although some vague and non-specific symptoms have been associated with it. Since iron is primarily required for hemoglobin, iron deficiency anemia is the primary clinical manifestation of iron deficiency. Iron ...

  4. Hemosiderin - Wikipedia

    en.wikipedia.org/wiki/Hemosiderin

    Hemosiderin or haemosiderin is an iron-storage complex that is composed of partially digested ferritin and lysosomes. The breakdown of heme gives rise to biliverdin and iron. [1] [2] The body then traps the released iron and stores it as hemosiderin in tissues. [3] Hemosiderin is also generated from the abnormal metabolic pathway of ferritin. [3]

  5. Respiration (physiology) - Wikipedia

    en.wikipedia.org/wiki/Respiration_(physiology)

    Exchange of gases in the lung occurs by ventilation and perfusion. [1] Ventilation refers to the in-and-out movement of air of the lungs and perfusion is the circulation of blood in the pulmonary capillaries. [1] In mammals, physiological respiration involves respiratory cycles of inhaled and exhaled breaths.

  6. Iron lung - Wikipedia

    en.wikipedia.org/wiki/Iron_lung

    An iron lung is a type of negative pressure ventilator, a mechanical respirator which encloses most of a person's body and varies the air pressure in the enclosed space to stimulate breathing. [ 1 ] [ 2 ] It assists breathing when muscle control is lost, or the work of breathing exceeds the person's ability. [ 1 ]

    Iron helps to strengthen the body's resistance to infections and diseases by facilitating the growth and health of immune cells. So, it is vital for the proper functioning of the immune system.

  8. Ferritin - Wikipedia

    en.wikipedia.org/wiki/Ferritin

    One major trigger for the production of many ferritins is the mere presence of iron; [9] an exception is the yolk ferritin of Lymnaea sp., which lacks an iron-responsive unit. [ 12 ] Free iron is toxic to cells as it acts as a catalyst in the formation of free radicals from reactive oxygen species via the Fenton reaction . [ 17 ]

  9. Cellular respiration - Wikipedia

    en.wikipedia.org/wiki/Cellular_respiration

    Cellular respiration is the process of oxidizing biological fuels using an inorganic electron acceptor, such as oxygen, to drive production of adenosine triphosphate (ATP), which contains energy. Cellular respiration may be described as a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical ...
