PNB 2265 LAB 6 QUESTIONS WITH
100% CORRECT ANSWERS .
path of respiratory histology - Correct Answer -nasal cavity, oral cavity, pharynx, larynx,
esophagus, trachea, primary bronchus, respiratory bronchiole, alveolus sac, alveolar
Wha t is the function of the respitory system? - Correct Answer -moves air into and out of the
lungs and exchange of O2 and carbon dioxide between the body tissues
upper respiratory tract includes - Correct Answer -nose, nasal cavity, pharynx, larynx
lower respiratory tract includes - Correct Answer -larynx, trachea, and bronchioles
gas exhange occurs in the - Correct Answer -respiratory zone
Alveoli are located in the - Correct Answer -respiratory zone
Alveoli - Correct Answer -air sacs in the lungs
conducting zone - Correct Answer -All the upper respiratory structures and all the lower
respiratory structures except the respiratory bronchioles
Hyaline cartilage rings are also present outside of the - Correct Answer -bronchiole
the respiratory bronchiole inner membrane is composed of - Correct Answer -pseudostratified
columnar epithelial tissue
The alveoli and capillary beds share _________________, which facilitates gas exchange. -
Correct Answer -simple squamous epithelial lining
1
, larger blood vessels also have a __________________, but additionally contain a thick, -
Correct Answer -simple squamous epithelial lining
irreversible loss of pulmonary gas exchange area due to inflammation and the destruction of
the terminal bronchioles and alveoli. - Correct Answer -emphysema
Emphysema causes destruction of - Correct Answer -pulmonary elastic connective tissue
Loss of this tissue decreases elastic recoil inside the lungs and leads to an - Correct Answer -
increase in diameter, or dilation, of the alveoli
An example of a bronchodilator is a - Correct Answer -beta-adrenergic receptor agonists
an infectious disease caused by various strains of mycobacteria transmitted by coughing or
sneezing - Correct Answer -tuberculosis
Aggregated cells like macrophages, T cells, B cells, and fibroblasts - Correct Answer -
granulomas
found within the granulomas are giant multinucleated cells that arise from the fusion of many
epithelial cells whose nuclei line the periphery of the cell. - Correct Answer -Langerhans
cells
a technique used to measure the amount of air that can be inhaled and exhaled from the lungs
- Correct Answer -Spirometry
what measures the volume of air moved with each breath - Correct Answer -spirometer
the volume of air that moves during a single inspiration/expiration cycle - Correct Answer -
tidal volume
lung volumes - Correct Answer -tidal volume, inspiratory reserve volume, expiratory reserve
volume, and residual volume
