Exam Questions and CORRECT Answers
Breathing - CORRECT ANSWER - inhalation and exhalation
Respiration - CORRECT ANSWER - gas exchange at level of the cell
what happens during respiration specifically - CORRECT ANSWER - CO2 out and bring
in O2
Ventilation - CORRECT ANSWER - moving air into and out of the lower airways
Primary role of breathing - CORRECT ANSWER - oxygen to cells and removal of carbon
dioxide
secondary role of breathing - CORRECT ANSWER - speech production
what does all speech sound require - CORRECT ANSWER - airflow from the lungs
Boyle's Law - CORRECT ANSWER - air flows from region of greater air density to
region of lesser air density
During inhalation, rib cage and lungs.. - CORRECT ANSWER - expand
when the rib cage and lungs expand in inhalation - CORRECT ANSWER - Volume
increases, negative air pressure inside lung and air rush in
during exhalation, rib cage... - CORRECT ANSWER - lowers
,when the rib cage lowers during exhalation... - CORRECT ANSWER - lungs with reduced
volume, positive air pressure inside lungs, and air rushes outward
What makes up the anatomy of the lower airway - CORRECT ANSWER - Rib cage,
Trachea, Bronchial Tree, AND Lungs
Rib cage is made up of - CORRECT ANSWER - 12 sets of ribs (left and right)
first 7 ribs are connected to.. - CORRECT ANSWER - the sternum
next 8-10 are attatched to the sternum but... - CORRECT ANSWER - indirectly through
cartilage
last two ribs are called - CORRECT ANSWER - floating ribs
Trachea - CORRECT ANSWER - about 11 cm.
tube made of cartilage forming C's with C opening towards the back
what connects the C's - CORRECT ANSWER - tissue
the trachea is a big pathway - CORRECT ANSWER - for airflow
Bronchial Tree - CORRECT ANSWER - branches at the end of trachea are bronchi
does the diameter of bronchi get smaller or larger with each division - CORRECT
ANSWER - smaller
how many divisions (roughly) does the bronchial tree have - CORRECT ANSWER - 38

left
Pleural linkage - CORRECT ANSWER - linkage between lungs and thorax
Two sides of pleural membrane - CORRECT ANSWER - parietal pleura and visceral
pleura
parietal pleura - CORRECT ANSWER - inside of rib cage and top of diaphragm
visceral pleura - CORRECT ANSWER - lining the surface of the lung
intrapleural space is filled with - CORRECT ANSWER - pleural fluid
What direction does the rib cage move - CORRECT ANSWER - front and back, left to
right, top to bottom
"Pump handle" motion of ribs is for the upper or lower ribs - CORRECT ANSWER -
upper
"pump handle" - CORRECT ANSWER - primarily front and upward displacement
small lateral displacement
