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).

Of every heart on earth infixes deep its restless twists:”

I am no more with life and death,
My heart upon his warm heart lies,
My breath is mixed into his breath.”
