HEART, n. [L. cor, cordis, and allied to Eng.core, or named from motion, pulsation.]1. A muscular viscus, which is the primary organ of the blood's motion in an animal body, situated in the thorax. From this organ all the arteries arise, and in it all the veins terminate. By its alternate dilatation and contraction, the blood is received from the veins, and returned through the arteries, by which means the circulation is carried on and life preserved.2.

The heart is deceitful above all things. Every imagination of the thoughts of the heart is evil continually.

The heart faints in adversity, or under discouragement, that is, courage fails; the heart is deceived, enlarged, reproved, lifted up, fixed, established, moved, &c.5. By a metonymy, heart is used for an affection or passion, and particularly for love. The king's heart was towards Absalom. 2 Sam. 14.6. The seat of the understanding; as an understanding heart.
