Heart

The heart is a hollow muscle that pumps blood throughout the blood vessels by repeated, rhythmic contractions. It is found in all animals with a circulatory system (including all vertebrates).

Famous quotes containing the word heart:

“And thus we rust Life’s iron chain
Degraded and alone:
And some men curse, and some men weep,
And some men make no moan:
But God’s eternal Laws are kind
And break the heart of stone:”
—Oscar Wilde (1854–1900)

“When the heart flies out before the understanding, it saves the judgment a world of pains.”
—Laurence Sterne (1713–1768)

“Miranda. My husband, then?
Ferdinand. Ay, with a heart as willing
As bondage e’er of freedom. Here’s my hand.
Miranda. And mine, with my heart in ‘t.”
—William Shakespeare (1564–1616)
