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:

“Hope deferred makes the heart sick, but a desire fulfilled is a tree of life.”
—Bible: Hebrew, Proverbs 13:12.

“My heart is warm with the friends I make,
And better friends I’ll not be knowing,
Yet there isn’t a train I wouldn’t take,
No matter where it’s going.”
—Edna St. Vincent Millay (1892–1950)

“What of the heart without her? Nay, poor heart,
Of thee what word remains ere speech be still?
A wayfarer by barren ways and chill,
Steep ways and weary, without her thou art,
Where the long cloud, the long wood’s counterpart,
Sheds doubled darkness up the labouring hill.”
—Dante Gabriel Rossetti (1828–1882)
