Match the haemostasis steps, labelled a. through j., with their correct characteristic(s). (Options may be used more than once or not at all.) a.converts fibrinogen to fibrin b.When platelets come into contact with this substance in an injured vessel wall, it causes them to adhere and aggregate. c.When activated, this substance digests the fibrin threads, causing dissolution of the clot. d.substance released by the platelet plug that causes more platelets to aggregate e.first step in haemostasis f.forms the meshwork of the clot g.a plasma protein activated by factor X h.second step in haemostasis i.released from injured tissues; activates extrinsic clotting pathway j.third step in haemostasis -thromboplastin
