Flashcards in Respiration Objectives Deck (14):
What are the parts of hte upper airway?
Mouth, Nasal Cavity, pharynx, larynx
What are the parts of the lower airway?
Trachea, Primary Bronchi, bronchi branches, lungs
Where does transfer of oxygen and CO2 take place?
Aveoli, and the smaller bronchi branches
What are the functions of the upper airway?
warm air, moisten air, filter air
What makes up the bulk of Lung Tissue?
Type 1 cells are involved in what process?
what doe type 2 cells create?
What is the importance of surfactant?
it helps the aveoli from sticking together and reducing their surface area.
Describe the Events of Inspiration
Alveolar pressure=to Atmospheric Pressure. Flow = 0
Inspiratory Muscles Contract. Thoracic Volume increases
Describe the Events of expiration
Elasticity of lungs compresses lungs. Alveolar Pressure increases, Flow= Outward.
What factors affect ventilation?
Lung Compliance, Surface Area of Aveoli, Diameter of Bronchi.
What is the difference between physiological and anatomical dead space?
Physiological dead space takes into account any aveoli that are not efficiently exchanging gases.
Describe the different lung volumes
Tidal Volumes-volume of air moved in single inhale
Inspiratory reserve-how much air you can take in after tidal volume
Expiratory reserve-how much air you can exhale after tidal volume
Residual Volume-how much air is left in lungs after max exhale
