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 Heart asks Pleasure—first—
And then—Excuse from Pain—”
—Emily Dickinson (1830–1886)

“O hiding hair and dewy eyes,
I am no more with life and death,
My heart upon his warm heart lies,
My breath is mixed into his breath.”
—William Butler Yeats (1865–1939)

“My heart is like a singing bird
Whose nest is in a watered shoot;
My heart is like an apple-tree
Whose boughs are bent with thickset fruit;
My heart is like a rainbow shell
That paddles in a halcyon sea;”
—Christina Georgina Rossetti (1830–1894)
