2-d) Analyse information from secondary sources to identify the products extracted from donated blood and discuss the uses of these products. ]Products which are extracted from donated blood include Red blood cells, White blood cells, platelets and plasma. RBS’s are given to patients who suffer Anaemia or have suffered excessive bleeding giving them cells which can carry oxygen around the body to the cells and remove wastes such as Carbon dioxide. WBCs’ are given to patients who need assistance in fighting infection include those with a low immune system. Plasma is given to patients whose blood volume is low, such as people who have suffered excessive bleeding; this gives them more medium to carry cells and nutrients whilst reducing the pressure on the heart to pump minimal blood around. Finally platelets are given to patients whose blood has trouble clotting, such as cancer and leukaemia patients
