Heart sickness

Heart Heart (h[aum]rt), 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[=o], Lith. szirdis, Russ. serdtse, Ir. cridhe, L. cor, Gr. kardi`a, kh^r. [root]277. Cf. {Accord}, {Discord}, {Cordial}, 4th {Core}, {Courage}.] 1. (Anat.) A hollow, muscular organ, which, by contracting rhythmically, keeps up the circulation of the blood. [1913 Webster]

Why does my blood thus muster to my heart! --Shak. [1913 Webster]

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 systemic 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 systemic 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. [1913 Webster]
