Respiratory System Flashcards
Where can you find the sternomanubrial angle?
in line with the 2nd rib
What is the main function of rib cage?
protection for lungs, heart, liver, esophagus, etc.
How many ribs articulate directly with the sternum?
Ribs 1-7
Only the first 7 ribs articulate directly with the sternum
Which ribs articulate with the costal cartilage?
ribs 8,9, and 10
Which ribs are the floating ribs? Do they articulate anything?
ribs 11 and 12
no, they don’t articulate anything
Which rib is an anatomical landmark for finding the distal tip of the scapula?
rib 7
Rib 12 is easily palpable from which anatomical side?
posterior
Rib 11 is easily palpable from which anatomical side?
laterally
What is the cervical spine range?
C1-C7
C1= atlas C2= axis
If you have a pt flex their neck, which part of the cervical spine is the most prominent? What is another name for this spot?
C7 is also called vertebral prominence
Where can you find the midclavicular lines?
runs through the left and right clavicle, and in line with nipples all the way down to abdominal region
Where can you find the scapula lines?
runs through the left and right inferior angles of the scapula all the way down to the lower back
Where are the lungs in relation to the rib cage?
the lungs protrude 2-4 cm above the clavicle, above the inner 1/3 of clavicle
the inner 1/3 of clavicle is protecting the lung apex
How far down do the lungs reach normal/average ribs anteriorly? What about a bigger person?
lungs are huge, they cross rib 6 and go down to rib 7
in a bigger pt, the lungs may reach to rib 8
How far down do the lungs reach normal/average ribs posteriorly? What about a bigger person?
lungs can project down to rib 10
in a bigger pt, it may go down to rib 12
What does bifurcates mean?
divide into 2 branches or forks
The trachea bifurcates into primary bronchi. What is this point called?
Carina
Where can you find the tracheal bifurcation point, Carina?
right behind the angle of Louis and in front of T4
What is the primary muscle for inspiration?
the diaphragm
What are the secondary muscles for inspiration?
external intercostal muscles
T/F
We don’t really need to use muscles for expiration because its passive
true
What does the parietal pleura line?
the thoracic cage (serous membrane)
What does the visceral pleura line?
covers/folds over the lungs
When would your body need to recruit more muscles for inspiration/expiration?
vigorous exercise, COPD, etc.
Where is the pleural cavity found? What is the cavity filled with? What is the purpose of this fluid?
it’s the space found between the parietal and visceral pleura
pleural cavity is filled with serous fluid
the fluid is there to reduce friction
Inspiration is always active breathing, however, if a pt has COPD, poor posture, or pneumonia, the respiratory system may need to recruit additional muscles for inspiration. What are these additional muscles?
accessory muscles, recruits the SCM and the scalene muscles
Expiration is typically passive, however active expiration is possible in patients with COPD, deep breathing exercises, stressful situations, etc. What muscles are recruited for active expiration?
abdominal muscles will help increase pressure to force air out
List a few examples of what a cough might indicate:
left sided heart failure congestion URI COPD smoking lungs bronchitis asthma
What is hemoptysis? What is it indicative of?
cough with blood streaks
indicative of ulcers, TB, CF, etc.
What is dyspnea?
difficult/labored breathing, SOB
What does wheezing sound like?
a whistling sound
What is tachypnea?
breathing too fast
What is paroxysmal nocturnal dyspnea?
SOB occasionally during sleep
