Increased erythropoietin production Increased heart rate Increased cardiac output Enhancement in oxygen extraction The answer for this question is b. increased heart rate. A reduction in tissue oxygenation as happens in anemia stimulates increased production of erythropoietin through a complex feedback mechanism. Increased production of erythropoietin enhances erythropoiesis in anemia. Increased extraction of oxygen in anemia is a compensatory mechanism that is mediated by an increase in 2, 3-diphosphoglycerate concentrations. Increased cardiac output is the main hemodynamic compensatory mechanism in anemia that aims to increase blood flow to the body organs. An increase in heart rate ...

The pathophysiological template of an ischemic stroke involving the dominant left hemisphere of the brain is usually caused by the arterial occlusion resulting from a thrombus that embolized from a more proximal anatomical structure in the body that is closer to the brain, such as the heart and lungs and arterial plaques. The thrombus may cause a significant occlusion to the major intracranial arteries like the middle cerebral artery which carries the blood flow to the frontal, parietal and temporal lobes. A left middle cerebral artery stroke will manifest a right hemiplegia and hemiparesis with the upper extremities more significantly affected than the ...
