Final answer:
Heparin does not result in vasodilation of blood cells, decreased capillary permeability, attraction of macrophages, or increased coagulation. Instead, it is an anticoagulant that works by inhibiting the formation of blood clots.
Step-by-step explanation:
The student has asked about the effect of heparin. Specifically, the question is: Heparin results in which of the following? a) Vasodilation of blood cells b) Decreased capillary permeability c) Attraction of macrophages to the area d) Increased coagulation e) None of the above. The correct answer is e) None of the above.
Heparin is an anticoagulant medication that helps to prevent the formation of blood clots by inhibiting certain factors in the coagulation system. It neither causes vasodilation specifically of blood cells, nor does it decrease capillary permeability, attract macrophages to the area, nor increase coagulation. Instead, heparin works mainly by activating antithrombin III, which then inhibits thrombin and factor Xa, leading to a decreased ability for blood to clot.
