| heart | To give heart to; to hearten; to encourage; to inspirit. "My cause is hearted; thine hath no less reason." (Shak) To form a compact center or heart; as, a hearting cabbage. 1. <anatomy> 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) 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. 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.

(Shak) "Peace subsisting at the heart Of endless agitation." (Wordsworth) 4. Courage; courageous purpose; spirit. "Eve, recovering heart, replied." (Milton) "The expelled nations take heart, and when they fly from one country invade another." (Sir W. Temple) 5. Vigorous and efficient activity; power of fertile production; condition of the soil, whether good or bad. "That the spent earth may gather heart again." (Dryden) 6. That which resembles a heart in shape; especially, a roundish or oval figure or object having an obtuse point at one end, and at the other a corresponding indentation, used as a symbol or representative of the heart. 7. One of a series of playing cards, distinguished by the figure or figures of a heart; as, hearts are trumps. 8. Vital part; secret meaning; real intention. "And then show you the heart of my message." (Shak) 9. A term of affectionate or kindly and familiar address. "I speak to thee, my heart."

| heart and lung transplant | A surgical procedure which replaces a diseased heart and lungs with a healthy heart and lungs from a donor.

They are not recommended for those with associated systemic disorders such as diabetes or autoimmune illness. Those with liver and/or kidney disease are also not candidates. Long-term outcomes are still being studied. (27 Sep 1997) |
