                    Annotations:

                    • 55% of blood pale yellow liquid 92% water - 8% solutes antibodies clotting proteins transports materials e.g. glucose, vitamins, salt carries heat serum - without clotting proteins
                    1. Erythrocytes

                      Annotations:

                      • red blood corpuscles bone marrow biconcave disc shape no nucleus no mitochondria rich in haemoglobin transports oxygen anaemia

                        Annotations:

                        • Defend the body against infection colourless no haemoglobin nucleus mitochondria some are phagocytes e.g. monocytes remove cell debris (some) produce antibodies (some) bone marrow + lymphatic tissue leukaemia
                        1. Monocytes (macrophages)

                          Annotations:

                          • Engulf pathogens, viruses, cancer cells, and tissues by phagocytosis formed in bone marrow 4-8% of the blood
                          1. Lymphocytes

                            Annotations:

                            • made in bone marrow and stored n parts of the lymphatic tissue e.g. spleen, lymph nodes, tonsils move using pseudopodia account for 20-25% of white blood cells produce antibodies
                          2. Platelets (thrombocytes)
