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 true colour of life is the colour of the body, the colour of the covered red, the implicit and not explicit red of the living heart and the pulses. It is the modest colour of the unpublished blood.”
—Alice Meynell (1847–1922)

“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)
