Final answer:
Aneurysm is the condition that describes the weakening of an arterial wall due to hypertension, atherosclerosis, and/or infection, which can cause the weakened area to balloon outward.
Step-by-step explanation:
The condition that describes the weakening of an arterial wall due to hypertension, atherosclerosis, and/or infection, which can cause the weakened area to balloon outward, is called aneurysm.
When a weakened arterial wall balloons outward, it forms a bulge, which is called an aneurysm. Aneurysms can occur in various parts of the body, including the brain, aorta (the main artery that carries blood from the heart to the rest of the body), and other arteries.
If left untreated, an aneurysm can rupture, leading to severe bleeding and potentially life-threatening complications. Treatment for an aneurysm may include medications, lifestyle changes, or surgical intervention, depending on the size and location of the aneurysm.
