- I should wish also that such persons were carefully shewn the eleven pellicles which, like so many small valves, open and shut the four orifices that are in these two cavities, viz., three at the entrance of the hollow vein, where they are disposed in such a manner as by no means to prevent the blood which it contains from flowing into the right ventricle of the heart, and yet exactly to prevent its flowing out; three at the entrance to the arterial vein, which, arranged in a manner exactly the opposite of the former, readily permit the blood contained in this cavity to pass into the lungs, but hinder that contained in the lungs from returning to this cavity; and, in like manner, two others at the mouth of the venous artery, which allow the blood from the lungs to flow into the left cavity of the heart, but preclude its return; and three at the mouth of the great artery, which suffer the blood to flow from the heart, but prevent its reflux.

Cyprus (/ˈsaɪprəs/), officially the Republic of Cyprus, is an island country in the eastern Mediterranean Sea, north of the Sinai Peninsula, south of the Anatolian Peninsula, and west of the Levant. It is geographically a part of West Asia, but its cultural ties and geopolitics are overwhelmingly Southeast European. Cyprus is the third largest and third-most populous island in the Mediterranean. It is east of Greece, north of Egypt, south of Turkey, and west of Lebanon and Syria. Its capital and largest city is Nicosia. The northeast portion of the island is de facto governed by the self-declared Turkish Republic of Northern Cyprus.
