Which term describes a bulge in the wall of an artery?

• A. Atherosclerosis
• B. Angina pectoris
• C. Aneurysm
• D. Myocardial infarction

Answer: (C)

A bulge in the wall of an artery is called an aneurysm. It’s a localized dilation that happens when the vessel wall weakens, and it can occur in arteries such as the aorta or those in the brain. Because the wall is stretched, aneurysms can be at risk of rupture, which can cause serious bleeding and requires monitoring or intervention depending on size and location. The other terms describe different problems: atherosclerosis is plaque buildup that narrows or blocks arteries; angina pectoris is chest pain caused by reduced blood flow to the heart muscle; myocardial infarction is heart muscle damage from a complete or prolonged loss of blood supply.
