Morphology

left + coronary + artery

The meaning is directly compositional: 'left' specifies side and modifies 'coronary artery' (an artery supplying the heart), so a learner who knows the constituent words can infer it refers to the coronary artery on the left side. Though medical in register, the noun-compound follows ordinary, literal semantics and is cross-linguistically parallel, making it transparent.

Etymology

Left coronary artery is a simple, descriptive name: left shows the side, coronary comes from a word meaning 'crown' because these arteries go around the heart, and artery is a blood vessel that sends blood. So the name tells you it is the main artery that sends oxygen-rich blood to the left side of the heart.
