Question

Quizplus · Accepted Answer

If the left ventricle of the heart fails, blood backs up in the pulmonary capillary, increasing capillary pressure and forcing fluid into the lungs. This can lead to pulmonary edema, which is the accumulation of fluid in the lungs. Option A is incorrect because pulmonary edema leads to an increase in plasma oncotic pressure, not a decrease. Option B is incorrect because lymph flow is not related to the pulmonary capillaries or the left ventricle of the heart. Option D is incorrect because an increase in plasma oncotic pressure would not cause pulmonary edema.
