What are the three processes for platelet plug formation?
Here are the three processes for platelet plug formation:1. Platelet adhesionThe platelets will adhere to the collage fibres exposed in a damaged blood vessel. This occurs when the glycoprotein 1b (GPb1) receptors of the platelets interact with the von Willebrand factor (vWb) synthesised by endothelium.2. Platelet activationThis process is initiated by the collagen fibres, the adenosine diphosphate (ADP), and thrombin. It causes the platelets to synthesise thromboxane A2 (TXA2) and to releasethe contents of their dense granules which contain ADP and 5-hydroxytryptamine.3. Platelet aggregationThe released mediators will cause the platelets to change from a discoid shape to a sphere with spiny projections. This new shape will increase the chances of the platelets making contact with other platelets. The platelets will then aggregate with fibrinogen and vWf as connecting agents via their glycoprotein IIb/IIIa receptors. ADP and TXA2 act as chemotactic factors to attract more platelets and the positive feedback loop created forms the platelet plug which temporarily seals the break in the damaged blood vessel.
