Pulmonary - Quiz 5: Exam 3 with || || || || || || ||
precise detailed solutions || ||
Two types of airways in the pulmonary system: - Correct answer ✔1. conducting
|| || || || || || || || || || || || ||
airways.
2. gas exchange.
|| ||
The conducting airways are involved in: - Correct answer ✔ventilation; mechanical
|| || || || || || || || || || ||
movement of air in/out of the lungs. Involves much of the initial airways.
|| || || || || || || || || || || ||
The gas exchange airways involves what function? - Correct answer ✔respiration and
|| || || || || || || || || || || ||
exchange of gas across membranes resulting in O2/CO2 gas exchange.
|| || || || || || || || ||
3 major airways of the conducting airway: - Correct answer ✔1. upper airways.
|| || || || || || || || || || || ||
2. larynx (laryngopharynx).
|| ||
3. lower airways.
|| ||
Two components of the upper airways: - Correct answer ✔1. nasopharynx.
|| || || || || || || || || ||
2. oropharynx.
||
What is the purpose if the larynx? - Correct answer ✔connects the upper and lower
|| || || || || || || || || || || || || || ||
airways. ||
,2
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 answer ✔1.
|| || || || || || || || || || || || || ||
trachea.
2. bronchi.
||
3. terminal bronchioles.
|| ||
The trachea deviates into: - Correct answer ✔the right and left main stem bronchus.
|| || || || || || || || || || || || ||
The split between the main bronchi is called: - Correct answer ✔carina.
|| || || || || || || || || || ||
Terminal bronchioles have small amounts of: - Correct answer ✔cartilage.
|| || || || || || || || ||
Most of the bronchioles are involved in: - Correct answer ✔the respiration/gas exchange
|| || || || || || || || || || || || ||
airway rather than the conducting airways.
|| || || || ||
3 major components of the gas-exchange airways: - Correct answer ✔1. respiratory
|| || || || || || || || || || || ||
bronchioles.
2. alveolar ducts.
|| ||
3. alveoli.
||
Describe alveoli: - Correct answer ✔small balloon like structures where the air ends; the
|| || || || || || || || || || || || ||
smallest unit of respirations.
|| || || ||
What cells make up alveoli walls? - Correct answer ✔epithelial cells.
|| || || || || || || || || ||
Types of epithelial cells: - Correct answer ✔1. Type 1 alveolar cells.
|| || || || || || || || || || ||
, 2
2. Type 2 alveolar cells.
|| || || ||
Difference between type 1 and type 2 alveolar cells: - Correct answer ✔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 answer ✔Surfactant is a protein that helps to
|| || || || || || || || || || || || || ||
reduce surface tension. || ||
surface tension in the lungs is a result of: - Correct answer ✔result of H+ binding to
|| || || || || || || || || || || || || || || || ||
water or other substances, like binding of lots of magnetic forces to pull everything
|| || || || || || || || || || || || || ||
tighter and closer together.
|| || ||
Surfactant acts like a : - Correct answer ✔detergent as it interferes with H+ bonds,
|| || || || || || || || || || || || || || ||
loosens everything and allows for easier inflation of alveoli.
|| || || || || || || ||
What occurs if a baby is born before surfactant is produced? - Correct answer ✔The
|| || || || || || || || || || || || || || ||
baby will have difficulty inflating its alveoli.
|| || || || || ||
Tx for baby born before surfactant production: - Correct answer ✔Give mother steroids
|| || || || || || || || || || || || ||
to enhance maturation process of these cells if known baby coming early.
|| || || || || || || || || || ||
The alveoli also contain these cells: - Correct answer ✔alveolar macrophages that engulf
|| || || || || || || || || || || || ||
pathogens, particles and debris causing an immune reaction.
|| || || || || || ||
The combination of the respiratory bronchioles, alveolar ducts, and alveoli is called: -
|| || || || || || || || || || || || ||
Correct answer ✔acinus. || ||
