PNB 2265 PRACTIAL II EXAM QUIZZES
WITH ACTUAL RIGHT ANSWERS .
normal lung tissue - Correct Answer -Terminal and respiratory bronchioles, alveoli
emphysema - Correct Answer -Destruction of bronchioles and alveoli leads to limited areas
for gas exchange. Symptoms (shortness of breath, intolerance for physical exertion) occur
when damage is already quite extensive. Treatment is administration of oxygen.
Teberculosis - Correct Answer -Infection by bacteria Mycobacterium Tuberculosis causes the
body's defense system to try to wall off foreign bacteria. This creates areas of fibrous scar
tissue which impacts airflow due to destruction of alveoli. Symptoms include coughing and
chest pain, fatigue, night sweats, weight loss. Treatment involves a strict regime of antibiotics
as TB has developed resistant strains due to individuals not completing treatment.
what are some differences between the right and left lung? - Correct Answer -the right lung
has three lobes whereas the left lobe has two lobes; both lobes have an oblique fissure, but
since the right lobe has an extra lobe compared to the left, it also has a horizontal fissure
Why are the right and left lungs slightly different in shape? - Correct Answer -the left lung
accommodates the position of the heart
what is the importance of the segmental lung design? - Correct Answer -The segmental lung
design allows for lobes to be removed and for the body to still function properly, should they
need to be removed due to disease or damage. The other lobes have the ability to compensate
for the lost lobe; for example in lung cancer, a lobotomy would remove the damaged tissue so
that the remaining portion of the lung can funciton normally.
branching of the bronchiole tree - Correct Answer -trachea
primary bronchi
secondary bronchi
tertiary bronchi
bronchioles
