The left auricle forms the posterior part of the base of the heart. Seven or eight pulmonary veins open into this cavity. Be- low, it communicates by the left auriculoventricular orifice, which is guarded by the bicuspid valve, with the left ventricle. The left ventricle discharges blood through the aortic orifice. This opening is guarded by the aortic semilunar valve similar to but stronger than the corresponding valve on the right side. All Digitized by Microsoft®.
