Lower respiratory tract: conducting portion, respiratory portion, conditioning (the incoming air, pulmonary circulation, bronchial circulation, pulmonary plexus. Lobar bronchi: segmental bronchi, bronchioles, terminal bronchioles, respiratory bronchioles, alveolar ducts, alveolar sacs. Alveoli: alveoli, alveolar type i cells, alveolar type ii cells, alveolar macrophages, pulmonary surfactant, respiratory membrane. Lungs: base, apex, costal surface, mediastinal surface, cardiac notch, cardiac impression, oblique fissure, superior lobes. Inferior lobes: horizontal fissure, middle lobe, bronchopulmonary segments, hilum, root. Inhalation: exhalation, forced inhalation, forced exhalation, external intercostals, serratus posterior superior, serratus posterior inferior. Internal intercostals: transversus thoracis, diaphragm, central tendon, phrenic nerve, boyles law, thoracic volume changes. Pseudostratified ciliated columnar (protection and movement of particles out of respiratory tract) - replaced by simple columnar, simple cuboidal, and eventually simple squamous (diffusion) Type ii al(cid:448)eolar cells; decreases surface te(cid:374)sio(cid:374) so that al(cid:448)eoli do(cid:374)"t collapse (cid:449)he(cid:374) air is (cid:373)o(cid:448)i(cid:374)g.
