Question
which type of muscle is the heart? (1 point) ○ involuntary muscle ○ stretch muscle ○ voluntary muscle ○ strong muscle
Brief Explanations
The heart is made of cardiac muscle, which is a type of involuntary muscle (it functions without conscious control). "Stretch muscle" is not a standard muscle classification term, "voluntary muscle" (like skeletal muscle) is under conscious control, and "strong muscle" is not a scientific classification. So the heart is an involuntary muscle.
