Respitory Flashcards
Upper respiratory tract
Nasal cavity, oral passage, pharynx, larynx
Lower respiratory tract
Trachea, bronchi, bronchioles, alveoli
Pharynx
The throat
Larynx
The voice box
Trachea
The windpipe
Bronchial tubes
Each bronchus enters one of the lungs and branches off
Alveoli
Air sacs where respiration occurs
Right lung lobes
3
Left lung lobes
2
Diaphragm
Controls inhalation and inspiration
When it contracts, the top moves inferiorly making the thoracic cavity larger
Boyles law
Pressure and volume are inversely related
Respiratory mechanics 1
Inhalation: flow of air into the lungs
Respiratory mechanics 2
Diaphragm contracts and moves downward
Respiratory mechanics 3
Thoracic cavity increases in volume and decreases in pressure
Respiratory mechanics 4
To equalize the pressure air flows into the lungs
