Explanation
Sustained hypertension can lead to several complications, including damage to the blood vessels in the retina (retinopathy), increased risk of stroke, and damage to the kidneys (renal disease). Other potential complications include heart disease, peripheral arterial disease, and cognitive impairment. It is important to manage hypertension through lifestyle modifications and medication to prevent these complications.
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.
