Anaemia
DefinitionAnaemia, which literally means "without blood," is a lack of red blood cells and hemoglobin. This results in a reduced ability of blood to transfer oxygen to different tissues. Hemoglobin is must to be present to ensure adequate oxygenation of all body tissues and organs. Anaemia is a condition where the level of hemoglobin in the blood is below the normal range. Hemoglobin is the iron-containing molecule in red blood cells that carries oxygen around the body so, in anaemia, less oxygen is delivered to the tissues. Anaemia is an abnormal reduction in the amount of the oxygen-carrying pigment hemoglobin in the red blood cells which are characterized by pallid skin, fatigue and breathlessness, and caused by blood loss, iron deficiency etc.
