Which effect results when von Willebrand factor (vWF) is deficient in a patient experiencing a laceration?

💡 Explanation

vWF is critical for platelet adhesion and subsequent aggregation at the site of injury. A deficiency impairs the initial binding of platelets to the exposed collagen in the vessel wall because vWF acts as a bridge. Therefore, impaired aggregation occurs, rather than enhanced stabilization or affecting the coagulation cascade directly.

• Why does skeletal fragility increase post-menopause even with adequate dietary calcium?
• Why does prolonged high-intensity exercise, like sprinting, result in muscle fatigue associated with burning sensations?
• A patient consistently feels hungry shortly after consuming a carbohydrate-rich meal. Which mechanism explains why this individual experiences early satiety failure?
• Why does focusing on a near object cause blurring of distant objects after prolonged near work?
