The aorta, p, The pulmonary artery.1, The hranch of the pulmonary artery that divides in the left lung. 2, The branchthat divides in the right lung. The divisions of this artery continue to divide and subdivide, until they becomeno larger than hairs in size. These minute vessels pass over the air-cells, representedby small dark points around the margin of the lungs. 345. The aorta proceeds from the left ventricle of theheart, and contains the pure, or arterial blood. This trunkgives off branches, which divide and subdivide to their ulti-mate ramifications, constituting the great arterial tree whichpervades, by its minute subdivisions, every part of the animalframe. This great artery and its divisions, with their return-ing veins, constitute the greater, or systemic circulation. What does this artery and its corresponding veins establish? Explainfig. 69. 345.

ANATOMY OF THE CIRCULATORY ORGANS. 161 arteries through the various tissues of the body. They arethinner and more delicate in structure than the arteries, sothat when emptied of their blood, they become flattened andcollapsed. The veins commence by minute radicles in thecapillaries, which are every where distributed through thetextures of the body, and coalesce to constitute larger andlarger branches, till they terminate in the large trunks whichconvey the dark-colored
