6. Place the following coagulation steps in the correct order. (Place a number 1 in the blank by the first step, a 2 in the blank by the second step, etc.) (7 marks) a) _Sticky fibrin threads form a web at the site of injury. b) _Both the intrinsic and extrinsic pathways result in the production of the enzyme prothrombin activator. c) _Thrombin transforms the soluble plasma protein fibrinogen into insoluble fibrin. d) _Red blood cells and platelets become trapped in the fibrin web to create a clot of fibrin, blood cells and platelets. e) _Prothrombin is converted to the enzyme thrombin. f) _Prothrombin activator acts on the globulin prothrombin (factor II). g) ___Damage to the inside of a blood vessel activates the intrinsic pathway. Damage to tissue outside blood vessels activates the extrinsic pathway. 7. Which of the following statements are true of erythrocytes? (Read carefully and select all the correct statements.) (3 marks) a) The protein hemoglobin contains the mineral iron. b) The mineral iron enables erythrocytes to carry oxygen. c) Erythrocytes pick up oxygen in pulmonary capillaries. d) The shape of an erythrocyte is best described as a deflated soccer ball. e) Hemoglobin that has given up its oxygen is called deoxygenated hemoglobin. f) The life span of an erythrocyte is about 60 days.
