Document Summary
Also endocrine role hormone production and secretion. Origin of supporting structures mesenchyme (from mesoderm: list the structures and describe the path of air through the conducting and respiratory passages of the lung. Respiratory system divided on to 2 portions: conducting portion. Terminal bronchioles: respiratory portion (gas exchange) Areas covered by olfactory epithelium responsible of sense of smell. Basal surface synapses with nerve fibres responsible for general sensation not olfaction. Olfactory glands (bowman"s glands) found in lamina propria (connective tissue below epithelium). Serous glands which release secretion on surface of olfactory mucosa odiferous substances become trapped and dissolve in secretion allows detection by olfactory receptors. Mucosa contains diffuse lymphatic tissue and nodules. Partially covered by stratified squamous epithelium, transition to respiratory epithelium. Mucosa contains lymphatic tissue and nodules as well as seromucous glands. Tube about 10-12 cm long and 2 cm in diameter. Wall is reinforced by 10 -12 horseshoe cartilage rings (open ends face posteriorly)
