🔬 Medical science
The lungs exchange oxygen and carbon dioxide across millions of alveoli. Major diseases include COPD and lung cancer (overwhelmingly tobacco-related), asthma, pneumonia (infectious) and pulmonary embolism.
Causation is supported by vast epidemiological datasets and molecular evidence; diagnosis uses imaging, spirometry, and biopsy, and treatment ranges from inhalers and antibiotics to surgery, radiotherapy and targeted/immune therapy.
🧩 The GNM model
Claimed conflict: GNM links the lung alveoli to a "fear of death" conflict — panic at a perceived mortal threat (one's own or a loved one's).
Germ layer & brain relay (GNM model): GNM classes the alveoli as endoderm tissue said to be controlled from the brainstem.
Two-phase course (claimed): GNM claims that during the conflict-active phase the alveolar cells proliferate (forming round lung nodules) and that during the healing phase mycobacteria caseate and break down this tissue, producing a TB-like picture.
