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:

“A glass of papaya juice
and back to work. My heart is in my
pocket, it is Poems by Pierre Reverdy.”
—Frank O’Hara (1926–1966)

“Be near me when my light is low,
When the blood creeps, and the nerves prick
And tingle; and the heart is sick,
And all the wheels of Being slow.”
—Alfred Tennyson (1809–1892)

“Camillo. Prosperity’s the very bond of love,
Whose fresh complexion and whose heart together
Affliction alters.
Perdita. One of these is true:
I think affliction may subdue the cheek,
But not take in the mind.”
—William Shakespeare (1564–1616)
