Morphology

heart + muscle

The meaning 'the muscle tissue of the heart' is directly and compositionally derived from combining 'heart' (the pumping organ) with 'muscle' (tissue that produces movement). This noun+noun compound follows a common, cross-linguistic pattern and is immediately predictable for a B1 learner who knows both constituents.

Etymology

Heart muscle is a simple picture: the heart is the body's 'pump' and the muscle is the strong tissue that squeezes it. So heart muscle means the tissue that makes the heart 'beat' and push blood.
