Anaemia. Illustration showing the microscope view of normal red blood cells (left) and those in three different types of anaemia (from left): iron-deficiency anaemia,megaloblastic anaemia and sickle cell anaemia. The test tube in the foreground contains a blood sample after separation in a centrifuge. At the bottom are red blood cells (red). Above this are white blood cells (blue) and plasma (yellow). Anaemia is caused by inadequate supply of oxygen in the blood due to a low concentration or abnormality of the oxygen-carrying blood pigment haemoglobin. Symptoms include headaches,lethargy,pallor and,in severe cases,dizziness and heart disorders | |
