Morphology
The phrase is partly compositional: a learner who knows 'histocompatibility' (the property allowing tissue transplantation) and 'complex' (a group of interrelated parts) can infer it refers to a group/assembly related to histocompatibility. However, the specific biological reference (a set of genes/proteins on chromosome 6 relevant to immune compatibility) is technical domain knowledge and not fully predictable from the parts for a B1 learner.
Etymology
Histocompatibility complex comes from parts meaning histo- 'tissue', compatibility 'a good match', and complex 'a group'. So, it paints a simple picture: a group of genes that help tissues 'match' each other, which is why the term refers to the genes that decide if a donated organ will be accepted or rejected.
