Which of the following indicates the proper sequence of tissue repair?

a) Organization, fibrosis and regeneration, scab formation, blood clotting, tissue damage
b) Tissue damage, blood clotting, scab formation, organization, fibrosis, regeneration

b) Tissue damage, blood clotting, scab formation, organization, fibrosis, regeneration

After tissue damage, a blood clot forms, which dries and forms a scab that will be replaced, via the process of organization, with granulation tissue, which, in turn, gives rise to regenerated tissue and fibrous scar tissue through the processes of regeneration and fibrosis.
