Function of the conducting zone
provides a fairly rigid conduits for air to reach the gas exchange sites.
which zone cleanses, humidifies and warm incoming air
conducting zone
passageway connecting nasal cavity to larynx and oral cavity to esophagus
pharynx
houses the tonsils
pharynx
passageway for air and food
pharynx
connects pharynx to trachea
larynx
had framework of cartilage and dense connective tissue
larynx
house vocal folds
larynx
prevents food from entering lower respiratory tract
larynx
mucosa-lined, air filled cavities in cranial bones surrounding nasal cavity
paranasal sinuses
descends from the larynx through the neck and into the mediastinum
trachea
located posterior to the nasal cavity, inferior to the sphenoid bone, and superior to the level of the soft palate
nasopharynx
serves only as an sir passageway
nasopharynx
formed by the fusion of two cartilage plates
thyroid cartilage
forms part of the lateral and posterior walls of the larynx
arytenoid cartilage
anchors the vocal folds
arytenoid cartilage
composed of elastic cartilage and is almost entirely covered by a taste bud-containing mucosa
epiglottis
guardian of the airways
epiglottis
one of the microscopic air sacs of the lungs
alveolus
one of the two large branches of the trachea that lead to the lungs
bronchus
branching air passageways inside the lungs that are smaller the 1 mm in diameter
bronchioles
the point where the trachea branches into the two main bronchi
carina
high sensitive and violent coughing is triggered when a foreign object makes contact with it
carina
covers the thoracic wall and superior face of the diaphragm
parietal pleura
continues around the heart and between the lungs, forming lateral walls of the mediastinal enclosure and snugly enclosing the lung root
parietal pleura
covers the external lung surface, dipping into and lining it fissures
visceral pleura
