the respiratory system is partners to what system?
cardiovascular system
what are the parts of the conducting portion of the respiratory system
nose nasal cavity pharynx larynx trachea smaller airways
parts of the respiratory portion
respiratory bronchioles
alveolar ducts
air sacs (alveoli)
functions of respiratory system
breathing (pulmonary ventilation)
2 types of gas exchange
external respiration
internal respiration
external respiration
gas exchange between the atmosphere and the blood
internal respiration
gas exchange between the blood and the cells throughout the body
structures that aid in sound production
lungs larynx nasal cavity paranasal sinuses teeth lips tongue
upper respiratory tract is composed of:
nose/nasal cavities
paranasal cavities
pharynx
this is the conducting portion
nose
main conducting airway
supported by nasal bones
roof of nasal cavity
frontal bone
nasal bones
cribriform plate of ethmoid
sphenoid bone
floor of nasal cavity
horizontal plate of maxillae
horizontal portions of the palatine bone
vestibule
anterior region of the nasal cavity
vibrassae
near vestibule are coarse hairs
conchae
aka turbinates, they create turbulence, allows the air to humidify and become warmer
superior nasal conchae
part of ethmoid bone
middle nasal conchae
part of ethmoid bone
inferior nasal conchae
independent facial bones
*nasolacrimal ducts empty just inferior of here
where is the resonationg chamber
nasal cavity
4 bones that contain paired air spaces (paranasal sinuses)
frontal
ethmoidal
sphenoidal
maxillary
how do the sinuses communicate with the nasal cavity
ducts and are lined by ciliated epithelium with overlying mucus
common spaced used by both the respiratory and digestive system
pharynx
3 regions of the pharynx
nasopharynx
oropharynx
laryngopharynx
oropharynx
both air and foodpass
no cilia
palatine anf lingual tonsils
