11.1 Conducting Zone Flashcards
Pulmonary ventilation
getting air into the lungs
Takes place in the conducting zone
External respiration
Gas exchange between air and blood
Takes place in respiratory zone
Transport gasses
Circulatory system transports CO2/O2
Takes place in blood
Internal respiration
Gas exchange between blood and tissues
Takes place in systemic capillaries
Four steps of respiration
- Pulmonary ventilation
- External respiration
- Transport gasses
- Internal respiration
Pharynx
Back of nasal and oral cavities
Respiratory system developed _____ your digestive
After, later
Little diverter
Larynx
Surface area of lungs
700-750 m^2
Modifications to air in the conducting zone
- Filtration (upper airway, pseudo-stratified ciliated columnar epithelium)
Goblet cells filled with mucus. - Adjusts Temperature
- Humidify
Vestibule
Entry to nasal cavity
Nasal conchae
Shelves in cavity covered in mucus
Gaps in between conchae
Turbinates
Para nasal sinus
Frontal, sphenoid, ethmoid, maxilla
Pharynx
Nasopharynx, oropharynx, lyrngopharynx
Soft pallet back of throat
Uvula
Epiglottis made of
Elastic cartilage
Thyroid cartilage
Adam’s apple
Cricothyroid ligament
Between thyroid and cricoid cartilage
Valsalvas maneuver
Close the larynx and exhaling (increasing inter-abdominal pressure)
Dozen or so rings of trachea are all
Hyaline cartilage
Lobes
3 right, 2 left
Primary bronchi
Aka main, stems off trachea
Secondary bronchi
Lobar
Tertiary bronchi
Segmental
Bronchioles don’t have
Cartilage (epithelium thinner)
