Final answer:
Hemophilia A is due to factor VIII deficiency, whereas von Willebrand's is due to von Willebrand factor deficiency. Hemophilia A is the most common form of hemophilia, accounting for approximately 80 percent of cases. Von Willebrand's disease is caused by a deficiency of von Willebrand factor.
Step-by-step explanation:
a) Hemophilia A is due to factor VIII deficiency; von Willebrand's is due to von Willebrand factor deficiency Hemophilia A is due to factor VIII deficiency, whereas von Willebrand's is due to von Willebrand factor deficiency. Hemophilia A is the most common form of hemophilia, accounting for approximately 80 percent of cases. In this disorder, there is an inability to synthesize sufficient quantities of factor VIII. On the other hand, von Willebrand's disease is caused by a deficiency of von Willebrand factor, which is necessary for platelet adhesion during clot formation.Hemophilia A and von Willebrand's disease are two distinct hereditary bleeding disorders. The correct answer to the student's question is: Hemophilia A is due to factor VIII deficiency; von Willebrand's is due to von Willebrand factor deficiency.
Thus, the correct option is (a).Hemophilia A is characterized by the inability to synthesize sufficient quantities of clotting factor VIII, which is essential for proper blood clotting. It is the most common form of hemophilia, accounting for about 80 percent of cases.On the other hand, von Willebrand's disease is caused by a deficiency of the von Willebrand factor (vWF), a protein that plays a key role in platelet adhesion and protection of factor VIII. People with von Willebrand's disease may have reduced levels of vWF or the vWF they have does not work properly.
