Respiratory Flashcards
1
Q
2 main portions of resp and functions
A
- respiratory - alveoli, gas exchange
2. conducting - warm, humdifies, filters
2
Q
4 layers of the trachea from in to out
A
- mucosa
- submucosa
- cart.
- adventitia
3
Q
structure of mucosa
A
pseudostratified columnar epithelium with goblet cells sitting on lamina propria
4
Q
6 types of cells in mucosa
A
- ciliated - move mucous
- goblets - sol phase of mucous
- basal - proliferate
- brush - sensory microvilli
- kulchitsky - neuroendocrine secretory cells
- dendritic - antigen presenting
5
Q
3 things making up submucosa
A
- loose connective tissue
- seromucous glands
- ducts
6
Q
feature of cart. rings
A
open on posterior with smooth muscle that connects called trachealis
7
Q
feat iof adventia
A
loose connective tissue surrounding cart.
8
Q
4 layers of bronchi
A
- mucosa
- submucosa
- cart.
- adventitia
9
Q
Diffs. between bronchi and trach.
A
- mucosa - some smooth muscle
- submucosa - same
- cart. - irregular and less prominent
- adventitia - same
10
Q
diffes between bronchi and bronchioles
A
- mucosa - even more smooth muscle
- submucosa - gone
- cart. - gone
- adventitia - merges with mucosa - has elastic to prevent collapse
11
Q
3 changes in mucosa in bronchioles
A
- lose the goblets
- then the cilia
- clara cells appear - secrete similar stuff to surfactant, progentiors
12
Q
enzyme that break down lung elastic
A
elastase
13
Q
4 parts of resp. part of lung
A
- resp. broncioles
- alveoli
- interalveolar septum
- alveolar/cap bed
14
Q
Feats . of resp. broncioles
A
broncioles broken by alveoli
- from the term bronchioles
15
Q
Feat of alveoli
A
polyhedral units
