Question: 1 / 400

What role does thromboplastin play after brain death?

Facilitates clotting

Thromboplastin plays a crucial role in the coagulation process, primarily functioning to facilitate clotting. After brain death, the body often experiences changes in hemodynamics, and the management of coagulation becomes particularly significant. Thromboplastin is instrumental in the transformation of prothrombin into thrombin in the coagulation cascade, which ultimately leads to the conversion of fibrinogen into fibrin, forming a blood clot. This process is vital in preventing excessive bleeding and maintaining hemostasis in individuals who may undergo organ donation or other medical interventions following brain death.

The other options, such as inhibiting healing, promoting oxygen delivery, or regulating blood pressure, do not directly pertain to the specific role of thromboplastin in the context of coagulation after brain death, which is why those choices do not align with the correct answer.
