The primary effect of thrombus formation is its ability to obstruct blood flow within the arteries. A thrombus, or blood clot, forms when platelets and fibrin accumulate at a site of vascular injury or in areas with disrupted blood flow, leading to a constriction or complete blockage of the blood vessel. This obstruction can hinder the delivery of oxygen and nutrients to the tissues supplied by the affected artery and can result in ischemia, tissue damage, or even necrosis if the blood supply is not restored.

The process of thrombus formation is a critical component in various cardiovascular pathologies, such as myocardial infarction or stroke, where timely restoration of blood flow is essential for tissue health. The other options do not reflect the actual impact of thrombus formation: it does not strengthen artery walls, ease circulation, or promote faster healing; rather, it has the opposite effects, contributing to potential complications in vascular health.
