Explain why cardiac muscle is classified as involuntary, and describe one reason why this is important for survival.

• Because it is attached to bones; it helps us move.

• Because it is controlled consciously; it allows us to stop our heart at will.

• Because it works without conscious control; this ensures the heart keeps beating to pump blood.

• Because it produces blood cells; this is necessary for oxygen transport.
