Describe the process of clotting as the conversion of fibrinogen to fibrin to form a mesh

State the functions of: (a) lymphocytes – antibody production (b) phagocytes – engulfing pathogens by phagocytosis

Identify lymphocytes and phagocytes in photomicrographs and diagrams

State the roles of blood clotting as preventing blood loss and the entry of pathogens

State the functions of the following components of blood: (a) red blood cells in transporting oxygen, including the role of haemoglobin (b) white blood cells in phagocytosis and antibody production (c) platelets in clotting (details are not required) (d) plasma in the transport of blood cells, ions, nutrients, urea, hormones and carbon dioxide

Identify red and white blood cells in photomicrographs and diagrams

List the components of blood as: red blood cells, white blood cells, platelets and plasma

Identify, in diagrams and images, the main blood vessels to and from the liver as: hepatic artery, hepatic veins and hepatic portal vein

Explain how the structure of capillaries is related to their functions

Explain how the structure of arteries and veins is related to the pressure of the blood that they transport
