Morphology
lower + respiratory + tract
The meaning is directly and transparently derived from the constituents: 'lower' (below), 'respiratory' (relating to breathing organs), and 'tract' (a bodily passage/system), so a learner who knows these words can infer it refers to the lower part of the respiratory system (bronchi and lungs). The compositional, medical terminology is canonical and mirrored across many languages, making the phrase immediately comprehensible to B1 learners who know the component words.
Etymology
Lower respiratory tract is a simple, literal name: lower shows it is the part below the throat, respiratory means 'breathing', and tract means a 'path' or area in the body. So the phrase points to the breathing parts lower in the chest, the bronchi and lungs.
