← Human Body & HealthWhich risk increases as Factor XII levels rise excessively in the blood?
A)Inadequate white blood cell migration
B)Elevated risk of thromboembolism✓
C)Reduced vascular permeability
D)Decreased inflammatory response
💡 Explanation
Elevated Factor XII triggers excessive activation of the intrinsic coagulation pathway, increasing thrombin generation and fibrin formation; this results in an elevated risk of thromboembolism because Factor XII initiates clotting cascade, therefore the clotting mechanism occurs excessively, rather than being appropriately regulated.
