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:

“Royalty is a government in which the attention of the nation is concentrated on one person doing interesting actions. A Republic is a government in which that attention is divided between many, who are all doing uninteresting actions. Accordingly, so long as the human heart is strong and the human reason weak, Royalty will be strong because it appeals to diffused feeling, and Republics weak because they appeal to the understanding.”
—Walter Bagehot (1826–1877)

“Although the stupid, unthinking world may approve what you have done, in your heart you know that, but for your treachery, the boy you loved would be alive today. If anyone is responsible for his death, you killed him, and for that murder you will live and die in the contempt and loathing of your own heart.”
—Karl Brown (1897–1990)

“O the cunning wiles that creep
In thy little heart asleep!
When thy little heart doth wake,
Then the dreadful night shall break.”
—William Blake (1757–1827)
