Document Summary

Conduction portion: nasal cavities, sinuses, pharynx, larynx, trachea, bronchi, bronchioles, terminal bronchioles. Respiratory portion: respiratory bronchioles, alveolar ducts, alveoli. Gas exchange, removal of particles, immune defense, control air flow. Alveoli: air sacs with thin walls of mostly blood vessels and simple squamous epithelium. Upper respiratory tract: nasal cavities, sinuses, pharynx. Through olfactory mucosa in nasal cavity smell. Bone with periosteum for sinuses & turbinate (nose) Cartilage rings and plates with perichondrium everywhere else. Smooth muscle, complete layers or small amounts. Air is warmed by vascular plexus and moistened by mucous and serous glands. Particles removed by vibrissae (hairs) and mucous. Nasal cavity has concha (projecting turbinate bones) to increase surface area, bone sinuses for air conditioning. Pseudostratified columnar epithelium with several cell types, all with common basal lamina. Small pyramidal cells at basal lamina (stem cells) Small granule cells at basal lamina, part of diffuse neuroendocrine system.
