GROUND
Grounded to UBERON:0009060 'air sac' (EXACT). Variant-match review (#12): the seeder grounds on exact labels only, so GOLD's slash and plural conventions hid a term that says exactly this. UBERON defines air sac as the membranous air-filled extensions of the lungs of birds, and the path is Birds > Respiratory system.
