Physical absorption of blood

Physical absorption of blood is a physiological or mechanical process rather than a specific molecular target such as a protein, enzyme, or receptor. In a clinical context, it refers to the capacity of hemostatic materials—such as sponges, gauzes, or polymers—to take up blood at an injury site [1]. This physical uptake concentrates platelets and endogenous clotting factors into a localized matrix, providing a physical scaffold that facilitates fibrin formation and the natural coagulation cascade [2]. While this mechanism is essential for managing surgical hemorrhage and trauma, it is a property of biomaterials and medical devices rather than a drug-targetable signaling molecule. Consequently, it does not meet the standard criteria for a therapeutic molecular target [3].
