Test 3.2 Flashcards
What is gas exchange
Between air from atmosphere and blood
What is ventilation
Air transport
What is respiration
Gas exchange
What does protection in the lungs guard you from
Guards respiratory membranes from dry air and inhaling pathogens
What’s the pathway of air through the respiratory system
Nose/nasal cavity Pharynx Larynx/glottis Trachea Bronchi Bronchioles Alveoli
Where does respiratory happen and where does ventilation happen
Ventilation happens between nasal cavity and bronchi
Respiratory happens between bronchioles and avleoli
What are the functions of Lungs
Gas exchange Moving air Protection Communication Olfaction (smell)
What is the glottis
Opening connecting pharynx to larynx
What is the epiglottis
Clovers the glottis
Prevents food from entering airway
What does bronchial tree/ avleoli consist of
Trachea divides into R and L bronchi
Bronchi divide into bronchioles
Bronchioles connect to alveoli
What does alveoli consist of
Tiny air sacs
Site of respiration (gas exchange)
Collectively make up respiratory membrane
What’s the respiratory defense system called
Nasal filtration
What does nasal filtration consist of
Nasal cavity lined with hairs
Filters out large particles
Nasal conchae which are boney ridges that stir air
The air we inhale contain?
Debris and pathogens
