Anemia (pronounced /əˈniːmiə/, also spelled In the early 18th century, English spelling was not standardized. Differences became noticeable after the publishing of influential dictionaries. Current British English spellings follow, for the most part, those of Samuel Johnson's Dictionary of the English Language , whereas many American English spellings follow Noah Webster's An American anaemia or anæmia; from Ancient Greek Ancient Greek is the historical stage in the development of the Greek language spanning the Archaic , Classical (c. 5th–4th centuries BC), and Hellenistic (c. 3rd century BC–6th century AD) periods of ancient Greece and the ancient world. It is predated in the 2nd millennium BC by Mycenaean Greek. Its Hellenistic phase is known as Koine (" ἀναιμία anaimia, meaning "lack of blood") is a decrease in normal number of red blood cells Red blood cells are the most common type of blood cell and the vertebrate body's principal means of delivering oxygen (O2) to the body tissues via the blood flow (through the circulatory system), as well as removing the cellular waste product, carbon dioxide (CO2) from the tissues and conveying it on their trip back to the lungs or gills, where it (RBCs) or less than the normal quantity of hemoglobin Hemoglobin is the iron-containing oxygen-transport metalloprotein in the red blood cells of vertebrates, and the tissues of some invertebrates in the blood.[1][2] However, it can include decreased oxygen-binding ability of each hemoglobin molecule due to deformity or lack in numerical development as in some other types of hemoglobin deficiency.
Since hemoglobin (found inside RBCs) normally carries oxygen Oxygen (pronounced /ˈɒksɨdʒɨn/, OK-si-jin, from the Greek roots ὀξύς (acid, literally "sharp", from the taste of acids) and -γενής (-genēs) (producer, literally begetter) is the element with atomic number 8 and represented by the symbol O. It is a member of the chalcogen group on the periodic table, and is a highly from the lungs to the tissues Tissue is a cellular organizational level intermediate between cells and a complete organism. Hence, a tissue is an ensemble of cells, not necessarily identical, but from the same origin, that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues, anemia leads to hypoxia Hypoxia is a pathological condition in which the body as a whole or a region of the body (tissue hypoxia) is deprived of adequate oxygen supply. Variations in arterial oxygen concentrations can be part of the normal physiology, for example, during strenuous physical exercise. A mismatch between oxygen supply and its demand at the cellular level (lack of oxygen) in organs. Since all human cells depend on oxygen Oxygen (pronounced /ˈɒksɨdʒɨn/, OK-si-jin, from the Greek roots ὀξύς (acid, literally "sharp", from the taste of acids) and -γενής (-genēs) (producer, literally begetter) is the element with atomic number 8 and represented by the symbol O. It is a member of the chalcogen group on the periodic table, and is a highly for survival, varying degrees of anemia can have a wide range of clinical consequences.
The three main classes of anemia include excessive blood loss (acutely such as a hemorrhage Bleeding, technically known as hemorrhaging or haemorrhaging is the loss of blood or blood escape from the circulatory system. Bleeding can occur internally, where blood leaks from blood vessels inside the body or externally, either through a natural opening such as the vagina, mouth, nose, ear or anus, or through a break in the skin. The complete or chronically through low-volume loss), excessive blood cell destruction (hemolysis Haemolysis —from the Greek Hemo-, Greek Αἷμα meaning blood, -lysis, meaning to break open—is the breaking open of red blood cells and the release of hemoglobin into the surrounding fluid (plasma, in vivo)) or deficient red blood cell production (ineffective hematopoiesis Haematopoiesis (or hematopoiesis in the United States; sometimes also haemopoiesis or hemopoiesis) is the formation of blood cellular components. All cellular blood components are derived from haematopoietic stem cells. In a healthy adult person, approximately 1011–1012 new blood cells are produced daily in order to maintain steady state levels).
Anemia is the most common disorder of the blood. There are several kinds of anemia, produced by a variety of underlying causes. Anemia can be classified in a variety of ways, based on the morphology of RBCs, underlying etiologic mechanisms, and discernible clinical spectra, to mention a few.
There are two major approaches: the "kinetic" approach which involves evaluating production, destruction and loss[3], and the "morphologic" approach which groups anemia by red blood cell size. The morphologic approach uses a quickly available and cheap lab test as its starting point (the MCV). On the other hand, focusing early on the question of production may allow the clinician more rapidly to expose cases where multiple causes of anemia coexist.
