Physiology Review Conducting Zone Made up of rigid passageways that serve to warm, moisten, and filter the inhaled air: nose, nasal cavity, pharynx, larynx, trachea, primary bronchi, tertiary bronchi, bronchioles, terminal bronchioles. Air passages undergo 23 orders of branching in the lungs which significantly increases cross sectional area for flow
