Fibrinolysis is provided by an enzymatic system that performs: Bbl6epute opuH oTBer: a. Proteolytic cleavage of fibrin b. Restoration of the vascular wall c. Limiting the spread of a blood clot during the process of stopping bleeding d. Maintaining blood in a liquid state due to natural anticoagulants

The correct answer is a. Proteolytic cleavage of fibrin.<br /><br />Fibrinolysis is the process by which a fibrin clot, the meshwork of protein strands that forms the basis of a blood clot, is broken down. This process is carried out by an enzymatic system that includes plasmin and its precursors, which perform the proteolytic cleavage of fibrin, breaking it down into smaller fragments that can be easily removed from the body.
