bleeding and blood clotting
Red blood cells (erythrocytes) trapped in a mesh of fibrin threads. Fibrin, a tough, insoluble protein formed after injury to the blood vessels, is an essential component of blood clots.
Clot retraction enhances the resilience of a blood clot by pulling the fibrin strands together, which makes the clot firm and permanent. During this process, the fibrin meshwork contracts and squeezes out its fluid contents. By condensing the structure in this way, the clot becomes a resilient, insoluble mass capable of withstanding the friction of blood flow.12
