Respiratory
General Functions of the respiratory system
- Gas exchange
- Regulation of blood pH
- Voice production
- Olfaction
- Protection
components of respiratory system
External nose, nasal cavities, pharynx, larynx, trachea, bronchi and lungs all lined with mucosa (epithelium and underlying lamina propria), upper espiratory tract and lower respiratory tract.
Upper Respiratory Tract includes:
Nose (including nasal cavities) and Pharynx
nasal cavities extends from….?
extends from external nares to internal nares (choanae)
parts of nasal cavity: External nares?
external opening
Parts of nasal cavity: Vestibule?
lined with hair (catches debris)
parts of nasal cavility: hard palate?
separates nasal and oral cavites (which bones form
this structure?)
parts of nasal cavity: soft palate?
separates nasopharynx from oropharynx
parts of nasal cavity: nasolacrimal duct?
drains tears from eyes into nasal cavity
parts of nasal cavity: nasal septum?
divides nasal cavity into right and left parts –
made of bone and cartilage
parts of nasal cavity: paranasal sinuses?
frontal, sphenoidal, maxillary and ethmoid air cells. hollow structures embedded in the bone of the skull that drain into the nasal cavities (not actually part of the nasal cavities - function is resonance
chonchae?
: 3 ridges of bone that cause turbulent air flow
allowing further contact of air with nasal mucosa
(warms, moistens and cleans air)
meatus?
tunnels from sinuses opening to nasal cavities
mucosa?
lining of the nasal cavity (epithelium and lamina
propria)
