Which muscle type is found in the heart?

Explanation:
The heart is made of a specialized muscle called cardiac muscle. This tissue contracts involuntarily to pump blood and is striated like skeletal muscle, but its cells are connected by intercalated discs that coordinate the heartbeat. This combination—involuntary control with a structure that enables rhythmic, synchronized contractions—is unique to cardiac muscle and distinguishes it from smooth muscle (found in walls of hollow organs and vessels) and skeletal muscle (voluntary, attached to bones). Red muscle refers to a type of slow-twitch skeletal fibers, not the heart. So the muscle type found in the heart is cardiac muscle.
