When a blood vessel is injured, what is the first response that takes place?Select one alternative:Exposed collagen fibres promote the adhesion of platelets to the site of injuryVascular spasm - smooth muscle cells of the damaged vessels constrict, reducing the amount of blood flow through the areaPrimary haemostasis: platelets immediately form a "plug" and stop blood lossA blood clot forms

Which of the following best describes a vascular spasm?Multiple choice question.long-term mechanism that triggers fibrin productionshort-lived mechanism in which the damaged vessel dilates, increasing blood flow and the amount of clotting agents at the site of the injuryshort-lived mechanism in which the damaged vessel narrows to minimize blood lossresponse of a capillary network to changing carbon dioxide levels
