14. A localized, abnormal dilation of a vessel is known as a(n):
arrhythmia
aneurysm
bradycardia
coarctation
Solution
The answer is the second one (B): aneurysm.
Explanation for each option:
Arrhythmia: This refers to an irregular heartbeat or abnormal heart rhythm. It is not related to the dilation of a vessel.
Aneurysm: This is the correct answer. An aneurysm is a localized, abnormal dilation or bulging of a blood vessel, usually an artery, due to a weakness in the vessel wall.
Bradycardia: This term describes a slower than normal heart rate. It is not related to the dilation of a vessel.
Coarctation: This refers to a narrowing or constriction of a vessel, typically the aorta, rather than a dilation.
In summary, an aneurysm is the term used to describe a localized, abnormal dilation of a vessel.
