Kahoot Review Flashcards
What is the function of cilia
Help with moving secretions
What type of cells normally move through the pores of kohn?
Macrophages
What is known as the amount of gas left over after a full exhalation?
Residual volume (RV)
True or False:
Surfactant increases compliance
True
Which part of the pleura is attached to the lungs?
Visceral
True or False:
Residual volume cannot be directly measured.
True.
It is calculated by subtracting the expiratory reserve volume from the functional residual capacity:
RV = FRC−ERV, OR RV = TLC−IVC.
What would increased resistance do to time constants (TC)?
Increase TC
What is the approximate amount of anatomical dead space in the average adult?
150 mL
Why is Carbon Monoxide (CO) diffusion limited?
True or False:
CO2 is 20x faster at diffusion across AC membrane than O2
True.
Affinity of CO2 is reduced in the presence of increased O2.
What is this phenomenon known as?
Haldane Effect
What is the normal extraction ratio value?
25%
What does ficks law of diffusion describe in simplest defintion?
Diffusion increases as surface area increases
True or False:
Stretch receptors in the lungs stop further inspiration.
True
Where are irritant receptors located?
large conduction airways
To be specific:
between and below the epithelial cells of the airways (larynx, trachea, bronchi, and intrapulmonary airways).
