Anemia

Anemia, also spelled anaemia (from the Ancient Greek a µ a anaîmia, meaning "without blood") is defined as a qualitative or quantitative deficiency of hemoglobin, a protein found inside red blood cells (RBCs). Since hemoglobin normally carries oxygen from the lungs to the tissues, anemia leads to hypoxia (lack of oxygen) in organs. Since all human cells depend on oxygen for survival, varying degrees of anemia can have a wide range of clinical consequences. Anemia is also caused by a lack of iron in the body. The three main classes of anemia include excessive blood loss (acutely such as a hemorrhage or chronically through low-volume loss), excessive blood cell destruction (hemolysis) or deficient red blood cell production (ineffective hematopoiesis).
