Explanation:

Question 21

Cardiomyopathy is a condition related to the heart muscle. "Cardio" refers to heart, "myo" refers to muscle, and "pathy" refers to disease. So the problem is with the muscle of the heart. Valves problems are valvular heart disease, coronary arteries problems are like coronary artery disease, and Purkinje fibers are part of the heart's conduction system, not related to cardiomyopathy.

Arteriosclerosis (arterio/sclera/o/sis) means hardening of the arteries. "Arterio" refers to artery, "sclero" means hardening, and "sis" is a suffix for condition. Cardiovavulitis is inflammation of heart valves, angiocarditis is inflammation of heart and blood vessels, and coronary thrombosis is a blood clot in coronary arteries.

Answer:

A. muscle
