Morphology

immune + system

The meaning is directly compositional: 'immune' (protected against infection) plus 'system' (an ensemble of cooperating parts) yields the system in the body that provides immunity. This is a literal, cross-linguistically common construction (e.g. Spanish 'sistema inmunológico'), so a learner who knows both constituents can readily infer the MWE meaning.

Etymology

Immune system is a name that gives a simple picture: immune suggests being 'safe from harm' and system means parts that work together. So it refers to the organs and cells in your body that work together to 'protect' you from germs and disease.
