Common pathway

Happens after either extrinsic or intrinsic pathways. Cleaves factor X to Xa. Makes thrombin form to prothrombin. Thrombin with calcium leads to thrombolysis. Fibrinogen forms crosslinked net that stabilises clot. Adhesion of clot is mediated by vWF binding to Gplb blocks ADP that enables Gpllb - llla to bind to fibrinogen.
