Heart \Heart\, n. [OE. harte, herte, heorte, AS. heorte; akin to
   OS. herta, OFies. hirte, D. hart, OHG. herza, G. herz, Icel.
   hjarta, Sw. hjerta, Goth. ha['i]rt?, Lith. szirdis, Russ.
   serdtse, Ir. cridhe, L. cor, Gr. ?, ? ????. Cf. {Accord},
   {Discord}, {Cordial}, 4th {Core}, {Courage}.]
   1. (Anat.) A hollow, muscular organ, which, by contracting
      rhythmically, keeps up the circulation of the blood.

            Why does my blood thus muster to my heart! --Shak.

   Note: In adult mammals and birds, the heart is
         four-chambered, the right auricle and ventricle being
         completely separated from the left auricle and
         ventricle; and the blood flows from the systematic
         veins to the right auricle, thence to the right
         ventricle, from which it is forced to the lungs, then
         returned to the left auricle, thence passes to the left
         ventricle, from which it is driven into the systematic
         arteries. See Illust. under {Aorta}. In fishes there
         are but one auricle and one ventricle, the blood being
         pumped from the ventricle through the gills to the
         system, and thence returned to the auricle. In most
         amphibians and reptiles, the separation of the auricles
         is partial or complete, and in reptiles the ventricles
         also are separated more or less completely. The
         so-called lymph hearts, found in many amphibians,
         reptiles, and birds, are contractile sacs, which pump
         the lymph into the veins.

   2. The seat of the affections or sensibilities, collectively
      or separately, as love, hate, joy, grief, courage, and the

      better or lovelier part of our nature; the spring of all
      our actions and purposes; the seat of moral life and
      character; the moral affections and character itself; the

      loving, bad, hard, or selfish heart.

            Hearts are dust, hearts' loves remain. --Emerson.

   3. The nearest the middle or center; the part most hidden and
      within; the inmost or most essential part of any body or
      system; the source of life and motion in any organization;
      the chief or vital portion; the center of activity, or of
      energetic or efficient action; as, the heart of a country,
      of a tree, etc.
