Respiratory Patho And Breathing Flashcards
Main structures of the Upper Respiratory Tract
Nose, Pharynx, Larynx
Main Structures of Lower Respiratory tract
Trachea, bronchi tree, lungs
Nose purpose
Passageway for air, moisten, examine for substance that may irritate the resp tract
Paranasal Sinuses
4 air filled cavities, mucous that drains into nasal cavity
Pharynx
Back of throat, divided into 3 parts, lined with mucous membranes
Tonsils
Site of immune reaction ,lymphatic tissue
Larynx
Triangle shaped cartilages, lined by mucous membranes to help remove dust and humidifies air
AKA voice box
Where is the epiglottis located
In Larynx, protects trachea from food and drink
Narrowest part of adult airway
Vocal cords
Narrowest part of a pedicatric airway
Cricoid ring
Vocal cords
Relaxed during normal breathing, contract and they produce sounds
Trachea
Windpipe, supports airway, bifurcates at the carina
Bronchial Tree
Passageway for air, removes all the rest of contaminants before alveoli
The alveoli
Enveloped in networks of capillaries, to accomplish gas exchange between air and blood
Lungs
2 coned shaped organs
Gas exchange happens here and it is most effective because of the massive surface area they provide
