Morphology
musculus + sphincter + pylorus
The term is directly compositional: 'musculus' (muscle) + 'sphincter' (a closing/regulating muscle) + 'pylori' (of the pylorus) yields 'the sphincter muscle at the pylorus' which controls passage from stomach to duodenum. Although technical and Latinized in form, this anatomical naming pattern is regular and cross-linguistically common, so a learner who knows the constituent meanings can infer the MWE meaning.
Etymology
Musculus sphincter pylori comes from old Latin and Greek words: musculus means 'little mouse' and was used for 'muscle', sphincter means 'to tighten', and pylori means 'gate'. So the name gives the image of a small ring that tightens like a gate, which is why it refers to the ring muscle that controls food leaving the stomach into the small intestine.
