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:

“Sweet is the day of sacred rest;
No mortal cares shall seize my breast;
O may my heart in tune be found
Like David’s harp of solemn sound.”
—Isaac Watts (1674–1748)

“Into my heart an air that kills
From yon far country blows:”
—A.E. (Alfred Edward)

“You took my heart in your hand
With a friendly smile,
With a critical eye you scanned,
Then set it down,
And said: It is still unripe,
Better wait awhile;”
—Christina Georgina Rossetti (1830–1894)
