KIN 435 Quiz #1 || 100% SOLVED!!
In a healthy adult human, tidal volume at rest is approximately: correct answers 500 mL
A participant is breathing normally at rest, the volume of gas that remains in the lungs after a
normal exhalation represents: correct answers Functional residual capacity
Which of the following is not involved in the central control of the respiratory system:
Cortex
Pons
Anterior pituitary
Medulla correct answers Anterior pituitary
A participant takes a maximal inhalation, followed by a maximal exhalation. The exhaled
volume of gas represents: correct answers Vital capacity
What is the correct order of airways starting from the trachea? correct answers Bronchi,
bronchioles, terminal bronchioles, respiratory bronchioles, alveolar ducts, alveolar sacs
Which of the following can be considered a portion of the blood-gas interface:
Basement membrane (BM)
Alveolar epithelium (EP)
Capillary endothelium (EN)
Interstitium (IN)
All of the above correct answers All of the above
Gas exchange in the lungs occurs:
Obeying Sheel's law
Diffusion from an area of high to low concentration
Active transport from an area of high to low partial pressure
Obeying Boyle's law correct answers Diffusion from an area of high to low concentration
In terms of regional differences in ventilation:
All regions of the normal lung have the same ventilation
Lower regions of the lung ventilate better than do the upper regions
Upper regions of the lung ventilate better than the lower regions
Distal regions of the lung ventilate better than the proximal regions
Proximal regions for the lung ventilate better than the distal regions correct answers Lower
regions of the lung ventilate better than do the upper regions
Regarding the blood-gas interface, which of the following is correct:
Large surface area
Is think to ensure stability
Because it is thick it can tolerate large increases in capillary pressure
Approximately 1 million alveoli
All are correct correct answers Large surface area
Regarding the respiratory center, which of the following is incorrect:
Located in the medulla and pons of the brainstem
Responsible for generating the rhythmic pattern of inspiration and expiration
