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:

“The blood weeps from my heart when I do shape,
In forms imaginary, th’ unguided days
And rotten times that you shall look upon
When I am sleeping with my ancestors.”
—William Shakespeare (1564–1616)

“The last time I saw Paris
Her heart was warm and gay.”
—Oscar Hammerstein II (1895–1960)

“The hapless Nymph with wonder saw:
A whisker first and then a claw,
With many an ardent wish,
She stretch’d in vain to reach the prize.
What female heart can gold despise?
What Cat’s averse to fish?”
—Thomas Gray (1716–1771)
