In 1905, Paul Morawitz consolidated a classical theory of blood coagulation. He described how tissue factor, prothrombin, calcium and fibrinogen interacted to form fibrin. Although later refined, this model organised knowledge of clotting and provided a foundation for anticoagulant research.

Morawitz's consolidation of the classical coagulation theory in 1905 marked a significant advancement in the understanding of bodily processes. This scientific ordering influenced modern writing about the body, intertwining themes of mechanism, mystery, and fragility in poetic explorations of human experience.
