GENERAL PLAN OF THE CIRCULATION. TiiK BLOOD IS CIRCULATED through the body, for the purposesof nutrition and secretion, by means of one forcing-pump, andthrough the lungs, for its proper aeration, by another; the twobeing united to form the heart. This organ is therefore a com-pound machine, though the two pumps are joined together, so as OENERAL PLAN OP THE CIRCULATION. 275. to appear to the casual observer to be one single organ. In com-mon language, the heart of the mammalia said to have two sides,each of which is a forcing-pump; but the blood, before it passesfrom one side to the other, has to circulate through one or otherof the sets of vessels found in the general organs of the body, andin the lungs, as the case may-be. This is shown at fig. 11,where the blood, commencingwith the capillaries on the gene-ral surface at (A), passes throughthe veins which finally end inthe vena cava (B), and entersthe right auricle (C). Fromthis it is pumped into (D) theright ventricle, which, contract-ing in its turn, forces it on intothe pulmonary artery (E), spread-ing out upon the lining mem-brane of the lungs, to form thecapillaries of that organ at F,from which it is returned to theleft auricle (Gr) through the pul-monary veins. From the leftauricle it is driven on to the leftventr
