Occurrence ;-The cardiac muscles occur in the heart.(in the walls of heart)

FUNCTION ARE:-

1.Cardiac muscles contract and relax rapidly , rhythmically and tirelessly throughout a life time .They contract endlessly from early embryonic stage until death.

2. The contraction and relaxation of the heart muscles help to pump and distribute blood to various parts of body.
