Test 3: Respiratory System Flashcards
The function of the respiratory system
Physically moving air in and out of the lungs by way of gas exchange at aveoli
Name the the first of the respiratory system
1.provides large area for gas exchange b/w air and the circulating blood
Second function of the respiratory system
Moves air along respiratory passageways to and from gas exchange surfaces of the lungs
Third function of the respiratory system
Protects resp surfaces from dehydration, temp changes and pathogens
Fourth function of the resp system
Produces sounds for speaking, singing and other forms of communication
5th function of the resp system
AIDS in sense of smell in the nasal cavity
Divisions of the respiratory system
Upper and lower respiratory systems
Describe the upper respiratory system
Nose, nasal cavity, pharynx, paranasal sinuses
These structures filter warm and humidifying air coming in
Describe the lower respiratory system
Larynx, trachea, bronchi, lungs
The lungs have bronchioles (air condutcion) and aveoli ( gas exchange)
Define the respiratory tract
Passageways carrying air to and from exchange of the surface lungs
2 portions of the respiratory tract
Conducting and respiratory
Explain the conduction portion
From nasal cavity to bronchioles
Filters warm and humidifying air
Explain the respiratory portion
Respiratory ( smallest and thinnest) bronchioles and aveoli
Site for gas exchange
