Atherosclerosis causes an aneurysm by
Causing ischemia of the intima
Increasing nitric oxide
Eroding the vessel wall
Obstructing the vessel
The Correct Answer is C
Atherosclerosis is a condition where plaque buildup occurs inside the arteries, which narrows the arterial lumen and limits blood flow. Aneurysms can occur as a result of atherosclerosis when the plaque formation weakens and damages the arterial wall, making it prone to bulging outwards or rupturing. This weakening of the vessel wall can cause it to lose its elasticity and strength, leading to the formation of an aneurysm. Therefore, the correct answer is C - eroding the vessel wall.

Correct Answer is C
Explanation
The left ventricle is responsible for pumping oxygenated blood out of the heart and into systemic circulation, which requires generating enough pressure to overcome the resistance of the systemic blood vessels. Therefore, the left ventricle has thicker and more muscular walls than the right ventricle and can generate higher pressures during contraction. In contrast, the right ventricle pumps deoxygenated blood to the lungs, which have lower resistance compared to the systemic circulation, and therefore do not need to generate as high pressures.
Correct Answer is C
Explanation
Infective endocarditis is an infection of the endocardium (the inner lining of the heart), which can lead to damage of the heart valves. It is most commonly caused by bacteria, although fungi and other microorganisms can also cause the condition.
