AnswerClick to flip back
A
Cardiac
💡 Explanation:
The heart is composed of cardiac muscle, which is a specialized type of muscle tissue found only in the heart. Cardiac muscle is striated (has bands) like skeletal muscle but involuntary like smooth (unstriated) muscle. The heart is NOT made of unstriated muscle (smooth muscle is found in organs like stomach and intestines), and sinuses are air-filled cavities, not muscle tissue.
