Platelets - are small colourless discs of cy lasm found in blood. When platelets come into contact with a damaged vessels 12 surface they change in several important ways. They begin to swell 13, their shape becomes irregular with protruding 14 processes, they become sticky and they release an enzyme 15 which causes the formation of thromboxane, one of the precursors 16 of thrombin. Thromboxane also activates 17 nearby platelets, thus starting a positive feedback which rapidly increases the mass of sticky platelets which form a platelet plug. This process accounts for daily damage to capillary 18 walls. Damage on a larger scale requires other mechanism 19 for haemostasis. Platelets also release serotonin which acts as a powerful vasoconstrictor
