An American text-book of physiology . Fig 104 -Diagram to illustrate the mechanism of Fig. to illustrate the mechanism of ? ? the semilunar valve. the semilunar valve and corpora Arantn. While the blood is streaming from the ventricle into the artery, the threesegments are pressed away by the stream from the centre of the vessel, butnever nearly so far as to touch its wall. At all times, therefore, a pouch ex-ists behind each segment, which pouch freely communicates with the generalcavity of the artery. As the ventricular systole nears its end, the ventricularcavity doubtless becomes narrowed just below the root of the artery, and withit the arterial aperture itself, while currents enter the sinuses of for a double reason the three segments of the valve are approximated,and probably the last blood pressed out of the ventricle issues through a nar-row chink between them. The instant that the pressure in the ventricle fallsbelow the arterial pressure, the three segments must be brought togethe
