The Respiratory System Flashcards
Function of respiratory system
Exchange of O2 and CO2
Inhalation
Taking air into the lungs
Exhalation
Taking air out of the lungs
Organs: in order
- Nose, nasal cavities
- Pharynx (throat)
- Larynx (voice box)
- Trachea (wind pipe)
- L and R primary bronchi
Functions:
-transport air
-make air warm = core body temperature
-make air clean
-make air humid
= lining the airways which is mucous membrane and secretes mucus
In lungs: Secondary bronchi Tertiary bronchi . . . Bronchioles Alveolar ducts Alveoli (place for exchange of O2 and CO2)
Organs: upper respiratory organs
Organs located in head and neck
Lining of the airways
Mucus membrane
Ciliated columnar epithelium
Goblet cell which secret mucous
Respiratory mucosa location
Nose Pharynx Larynx Trachea Bronchi (all)
Nose: nasal cavities
Lining: respiratory mucosa is call nasal epithelium
Nasal septum
Cartilage
Vomer bone
Ethmoid bone
Nose septum
The wall between two nasal cavities
Conchae
Increase surface of the nose
Line with nasal epithelium
Make more air clean, warm, and humid
Floor of the nose is called
Palate
Hard palate
4 bones, palatine, maxillary
Soft palate
Uvula
Paranasal sinuses:
Frontal
Maxillary
Ethmoid
Sphenoid
“para” meaning around
Around the nose and open to nose
Functions: make skull lighter, voice better, participate in sense of smell
Contain air
stops food from entering to trachea
