Which term refers to ballooning of arterial walls due to weakness?

Explanation:
Aneurysm is the term for ballooning of arterial walls due to weakness. When a segment of an artery has a weakened wall, it can stretch outward under the pressure of blood, forming a bulge or sac. This dilation is the defining feature, distinguishing it from other vascular problems. Angina is chest pain from reduced blood flow to the heart muscle, not a dilation. An embolism refers to a traveling blockage that can obstruct a vessel, and a thrombus is a blood clot that forms in place and can also obstruct flow. So the word that matches ballooning of the artery is aneurysm.
