Blood is made up of liquids (called plasma) and solids consisting of red and white blood cells and platelets.
Disruption of the plasma, red or white blood cells or platelets affects blood function. Blood disorders can be inherited (such as haemophilia and von Willebrand disease) or caused by other problems like lack of nutrients in the diet (anaemia) and cancers (leukaemia).
