【評論內容】Egan's 10th p220The cardiovascular system has two different sets of baroreceptors.The first set is located in the aortic arch and carotid sinuses.These receptors monitor arterial pressures generated by the left ventricle.The second set is located in the walls of the atria and the large thoracic and pulmonary veins.These low pressure sensors repond mainly to changes in vascular volumes.
