RT Egan's Fundamentals CH. 9
1.What is the primary purpose of the respiratory system?: Continuous
absorp- tion of oxygen (O2) and excretion of carbon dioxide
2.What is meant by "internal respiration"?: Exchange of gases between
the blood and the tissue
3.By what mechanism does gas exchange across the lung occur?:
Simple diffusion
4.What is unique regarding the blood supply to the lung?: It receives blood
from right and left ventricles
5.Running vertically down each hemithorax anteriorly is an imaginary line
that is used as an anatomical landmark. What is that line called?:
Midclavicular line
6.What is the function of the thorax?: Protect the vital organs
7.What is the name of the thin serous membrane that covers the inner
1/
17
,layer of the thoracic wall?: Parietal pleura
8.What is the name of the upper portion of the sternum?: Manubrium
9.Where does the sternal angle lie?: At the join between the
manubrium and sternal body
10.What is the name of the external landmark that identifies the point at
which the trachea branches into the right and left main stem bronchi?:
Sternal angle
11.The intercostal arteries, veins, and nerves run through which of the
follow- ing?: Costal groove on the bottom of each rib
12.What does the "pump handle" movement of rib pairs 2 through 7
achieve?-
: Increase in the anteroposterior diameter of the chest
13.Which of the following muscles are considered primary muscles of
venti- lation?
1. Diaphragm

, 2. Intercostals
3. Scalenes
4. Sternomastoid: 1 and 2
14.What external landmark can be used to show the highest point the dome
of the right hemidiaphragm reaches in a healthy individual?: Eighth rib
posteriorly
15.Approximately what percent of the normal changes in thoracic
volume during quiet inspiration is due to the action of the diaphragm?:
75%
16.How far is the diaphragm pulled down during tidal breathing?: 1 to 2 cm
17.Compared to a normal diaphragm, contraction of a diaphragm that is low
and flat may result in which of the following?: Compression of the thoracic
cavity
18.What pulmonary disorder could lead to acute flattening of the
diaphragm?-
