Understanding Patho: Pulmonary -
Quiz 5: Exam 3 Questions and verified
answers
what causes this? ✔️✔️Correct Ans-right ventricular enlargement caused by chronic pulmonary HTN.
Cor pulmonale progressed to: ✔️✔️Correct Ans-right ventricular failure if the pulmonary HTN is not
reversed.
Two types of airways in the pulmonary system: ✔️✔️Correct Ans-1. conducting airways.
2. gas exchange.
The conducting airways are involved in: ✔️✔️Correct Ans-ventilation; mechanical movement of air
in/out of the lungs. Involves much of the initial airways.
The gas exchange airways involves what function? ✔️✔️Correct Ans-respiration and exchange of gas
across membranes resulting in O2/CO2 gas exchange.
3 major airways of the conducting airway: ✔️✔️Correct Ans-1. upper airways.
2. larynx (laryngopharynx).
3. lower airways.
Two components of the upper airways: ✔️✔️Correct Ans-1. nasopharynx.
2. oropharynx.
What is the purpose if the larynx? ✔️✔️Correct Ans-connects the upper and lower airways.
Has a switching mechanism that only allows airway to be available in the breathing portion. Also
functions for voice production.
3 components of the lower airways in the conducting airways: ✔️✔️Correct Ans-1. trachea.
2. bronchi.
, 3. terminal bronchioles.
The trachea deviates into: ✔️✔️Correct Ans-the right and left main stem bronchus.
The split between the main bronchi is called: ✔️✔️Correct Ans-carina.
Terminal bronchioles have small amounts of: ✔️✔️Correct Ans-cartilage.
Most of the bronchioles are involved in: ✔️✔️Correct Ans-the respiration/gas exchange airway rather
than the conducting airways.
3 major components of the gas-exchange airways: ✔️✔️Correct Ans-1. respiratory bronchioles.
2. alveolar ducts.
3. alveoli.
Describe alveoli: ✔️✔️Correct Ans-small balloon like structures where the air ends; the smallest unit of
respirations.
What cells make up alveoli walls? ✔️✔️Correct Ans-epithelial cells.
Types of epithelial cells: ✔️✔️Correct Ans-1. Type 1 alveolar cells.
2. Type 2 alveolar cells.
Difference between type 1 and type 2 alveolar cells: ✔️✔️Correct Ans-Type 1 - alveolar structure
components like endothelial cells in capillaries that allows for exchange across capillaries (part of the
alveoli capillary membranes).
Type 2 - produces surfactant.
Why is surfactant important? ✔️✔️Correct Ans-Surfactant is a protein that helps to reduce surface
tension.
