What happens to the artery wall in an aneurysm?

1. It becomes thicker

2. It weakens

3. It constricts

4. It becomes more elastic

The correct answer is: It weakens

In the case of an aneurysm, the artery wall becomes weaker due to a localized dilation or bulging in that area. This weakening generally occurs because the structural components of the artery wall, such as collagen and elastin, become compromised. Factors contributing to this condition may include high blood pressure, cholesterol levels, and certain genetic conditions that affect the integrity of blood vessel walls. The weakened wall can lead to an increased risk of rupture, which can have serious and life-threatening implications. Understanding this weakening process is crucial for recognizing the potential dangers associated with aneurysms and the need for medical monitoring or intervention.
