parietal pleura
the diaphragm is ___bone/muscle___
muscle
the _____ is where vessels enter and exit the lungs
hilum
even though the RT lung has 3 lobes it is a bit shorter than the LT lung. why?
due to the liver
even though the LT lung has 2 lobes it is a bit longer than the RT, however is ___bigger/smaller___. why?
LT lung is long and small - as the heart takes up a big portion of space

true
the inner pleura that covers the lungs, is called what?
visceral pleura
between the pleura is the ____ space
pleural space
at the inferior aspect of the lungs is a domed shaped muscle, what is it called?
diaphragm
label the diagram of the lungs -
A. trachea
B. bronchi
C. upper
D. Lower
E. Upper
F. diaphragm
G. ribs
what does the diaphragm separate?
lungs from the abdomen
the diaphragm helps us breath how?
by forcing air in & out of the lungs
T/F: when we breathe, there is a specific order of airflow
true
what is order of airflow? (7 steps)
- nose/mouth
- trachea
- primary bronchi
- secondary bronchi
- tertiary bronchi
- bronchioles
- alveolar ducts
our wind pipe is also known as the ___
trachea
the ____ divides/bifurcates into primary bronchi
trachea
the bifurcation of the trachea is also known collectively as the _____
carina
the carina is located at what level?
T4-T5
primary bronchi divide into what?
secondary and tertiary bronchi –> which continue to divide down into bronchioles
______ are air sacks that exchange oxygen and carbon dioxide
alveoli
what are the main risk factors of lung cancer?
smoke, radon exposure, asbestos exposure
asbestos exposure leads to an increased risk of getting what type of lung cancer?
mesothelioma
____ is the number risk of lung cancer
smoke/smoking - cigarette, cigar, second hand, firsthand
radon exposure can increase chances of _____ cancer
lung
_________ is a carcinoma that starts in the pleura/lining
mesothelioma
T/F: lung cancers typically do not have signs and symptoms until later more advanced stages
true
what are symptoms of lung cancer? (8)
- persistent cough
- coughing up blood
- shortness of breath
- chest pain
- hoarseness
- weight loss w/o trying
- bone pain
- headache
what are the 2 major histopathology’s of lung cancer
small cell lung cancer (SCLC) AND non-small cell lung cancer (NSCLC)
_______ lung cancer is also called “oat cell”
SCLC (small cell lung cancer)
__SCLC/NSCLC__ makes up 10-15% of all lung cancers
SCLC
which is more aggressive - NSCLC or SCLC
SCLC
what is main risk factor of developing SCLC
- smoking tobacco
which is more common near the central region of lungs near bronchi? - SCLC or NSCLC
SCLC
would you rather have a tumor in center of lungs or on periphery?
periphery tumor, has better prognosis than a centrally located tumor
what treatment is used with SCLC as it tends to spread quickly.
PCI (Prophylactic cranial irradiation)
which lung cancer histology is more common? - NSCLC or SCLC
NSCLC
T/F: more than half patients with SCLC have spread at time of diagnosis, beyond supraclav area; extensive disease
true
T/F: SCLC responds well to chemo and radiation, however - they are not considered a cure as SCLC has high likeliness of metastasis
true
T/F: it is very likely for patient’s with SCLC to develop a CNS metastasis
true
___SCLC/NSCLC___ makes up 80-85% of all lung cancers
NSCLC
what are the 3 subtypes of NSCLC?
adenocarcinoma, squamous cell carcinoma, and large cell carcinoma
which subtype of NSCLC is NOT associated with cigarette smoking?
adenocarcinoma
which subtype of NSCLC is more common in women?
adenocarcinoma
adenocarcinoma subtype of NSCLC is found commonly where in lung? central or periphery
periphery
which subtype of NSCLC IS associated with tobacco smoking?
squamous cell carcinoma (SCC)
Adenocarcinoma or Squamous cell carcinoma is found in lining of the airways
SCC (squamous cell carcinoma)
what subtype of NSCLC can occur anywhere in the lungs and grows quickly
large cell carcinoma
which subtype of NSCLC is NOT associated with smoking/patients that do not have a history of smoking?
adenocarcinoma
squamous cell carcinoma or adenocarcinoma - starts in the cells that line the alveoli and make mucous
adenocarcinoma
describe the staging of SCLC - *hint it can be split into two
limited stage and extensive stage
describe the NSCLC staging - *hint it can be split into two
clinical stage and pathologic stage
the following is describing which stage of SCLC? - limited or extensive

- limited to lymph nodes on ipsilateral side
- can include ipsilateral supraclavicular nodes & mediastinal lymph nodes
limited SCLC
the following is describing which stage of SCLC? - limited or extensive
-spreads to both sides of lung
- spread to lymph nodes on either side
- spread to other body parts
extensive SCLC
the following is describing which stage of NSCLC? - clinical stage or pathologic stage
- uses physical exam
- biopsy
- imaging tests
clinical stage NSCLC
the following is describing which stage of NSCLC? - clinical stage or pathologic stage
