Document Summary
Alpha is inactive until activated: fibrinogen responsible for clotting mainly , inactive until activated to form blood clots, turns into fibrin when activated and becomes insoluble for clotting, reaction catalyzed by thrombin. 5 mill per cubic meter: oxygen transport mainly, concave discs to have large surface area. Red blood cell enzymes: responsible for co2 transport in rbc. Anemia: below oxygen carrying capacity of the blood. Polycythemia: too many rbcs and high blood cell count, primary- tumor conditions, uncontrolled production of rbcs, secondary adaptive mechanism to increase o2 carrying capacity from prolonged oxygen delivery, a lot of blood = high blood pressure. Leukocytes (white blood cells: have no haemoglobin so no colour. Platelets: called thrombocytes, no nuclei, high actin and myosin concentrations, generate secretory products, activated by collagen, function for 10 days and then removed by macrophages, spleen and liver, main function to help stop bleeding.
