Answer to Question 1

ANS: D
About 80 of heart attacks and 85 of strokes in the United States are caused by thrombi that block coronary or carotid arteries.

Answer to Question 2

ANS: B
Thrombosis is the inappropriate formation of platelets or fibrin clots that obstruct blood vessels. Thrombophilia refers to congenital abnormalities that increase the risk of thrombosis; factor V Leiden is one such risk factor. An embolus forms when a piece of a thrombus breaks off and travels to another location via the circulatory system.
