Sēo gerinnungendebyrdness cann mann sceortlīce amearcian þus: -

  1. Flǣscmasctimberpæþ: þæt hēafodƿeorc þisses pæðes is tō forþberenne gemet gerinnunginƿyrcendes. Gerinnunginƿyrcend is se ānlīca hefigosta dǣl þǣre gerinnungendebyrdnesse gif mann smēage his andsƿara onginnes ƿeorc. FVIIa begǣþ on mārum gemete þonne ǣnig ōðer ongunnen gerinnungtimber, and æfter gederunge on þǣre ǣdrinrinde is flǣscmasctimber (TF) forþsend, and þis þǣr ƿierþ æglīmtimbermanigfealdness mid FVIIa (þēos manigfealdness hāteþ TF-FVIIa) and þis onginþ FIX and FX. FVII self is ongunnen fram gerinnunginƿyrcende, FXIa, blōdclottspēntōlȳsunginƿyrcend, FXII, and XFa. Þæt onginn FXa fram TF-FVIIa is nēan sōna forseted fram flǣscmasctimberhremminge (TFPI). FXa and his efentimber FVa ƿyrcaþ þā fōregerinnunginƿyrcendtimbermanigfealdnesse þe aƿendeþ fōregerinnunginƿyrcend tō gerinnunginƿyrcende. Gerinnunginƿyrcend þonne onginþ ōðre dǣlas þǣre gerinnungendebyrdnesse, ēac FV and FVII (þe ƿierþ FXI and þā þā FIX), and onginþ and lȳseþ FVIII fram bindunge tō vWF.
