Bronchials Flashcards
Describe the Bronchial tree largest lobe to the smallest lobe?
Main bronchi
Lobar(secondary)
Segmental(tertiary)
Bronchioles -branches of the teriatry lack of cartilage
If you accidentally inhale something where is the lob most likely to enter ?
Right primary bronchus
In the Main(primary) Bronchi what is the Cartilage rings replaced for ?
Replaced by irregular and cartilage plates
What is the difference right and left bronchus
Right bronchus is wider, shorter, and more vertical than left
what are the three lobes of the Left lung ? Starting at the top
Superior lobe
Middle lobe
Inferior lobe
how many lobes does the left lung have ?
2
What is a bronchial plumary segment ?
That is what branches off the primary brondrius
What branch of the Bronchial tree lacks cartilage
the bronchioles
What does smooth muscle help with?
It helps to contract and relax the flow of the air through the airway
What are the layers of the Bronchus starting from the lumen ?
Pseudostratified epithelium
Lamina propia
smooth mucsle
cartilage
Smooth muscle wraps around Bronical tree where is this smooth muscle absent ?
Smooth muscle is absent around the alveoli
Whats the difference between alveoli and the alveolar ?
Alveolar refers to the sac of alveoli where alveoli are the individual pieces of the alveolar sac
Why would smooth muscle be absent around the alveoli ?
It would be absent because the blood would exchange oxogen and carbon dioxide there would no longer need to be a control of the air going in and out of the lungs
On the Bronchial tree starting at the top or the largest portion how does the cartilage look?
Regular plates, irregular plate, to none
Where on the Bronchial tree are their irregular cartilage?
this would be be in the mid portion
