Morphology
The phrase is directly compositional: 'cardiac' means related to the heart and 'muscle' is body tissue that contracts, so a learner who knows both words can infer it refers to the heart's muscle tissue. This is a standard technical noun phrase with the same logic in many languages, so its meaning is transparent to learners familiar with the constituents.
Etymology
Cardiac muscle comes from two old words: cardiac from a Greek word for 'heart' and muscle from a Latin word that meant 'little mouse' because people thought moving muscles looked like mice under the skin. So cardiac muscle simply means the muscle of the heart, the special tissue that keeps it beating all the time.
