19
Q

what do club cells do

A

secrete SURFACTANT, enzymes that DETOXIFY inhaled xenobiotic compounds, antimicrobial peptides and cytokines

20
Q

chemosensory brush cells

A

DNES (diffuse neuroendocrine system) small granule cell (detect irritants)

21
Q

type I pneumocytes/ alveolar cells

A

REMOVE SURFACTANT and small particulate contaminants party though pinocytosis
contains SIMPLE SQUAMOUS cells which are thin and thus good for diffusion

22
Q

type II pneumocytes / alveolar cells

A

contain lamellar bodies contiaining lipids, phosphilipids, and proteins that make up pulmonary surfactant, SIMPLE CUBODIAL

23
Q

alveolar macrophages (dust cells)

A

immune cells present in both the alveoli and in the interalveolar septa

24
Q

respiratory epithelium is what type

A

psuedostratified columnar epithelium

25

nasal pharynx communicate w what

A

choanae

26
Q

vestibular fold what gland or no gland, what cell type

vocal fold what gland or no gland, what cell type

A

respiratory epithelium, lamina propria contains seromucous glands

vocal folds stratified squamous epithelium, no glands

27
Q

where are clara/club cells

A

bronchioles

28
Q

mesothelium what type of cells

A

simple squamous epithelium

29
Q

how does adenylyl cyclase work and what does it do

A

ATP -> cAMP
cAMP activates PKA to phosphorylate serine/theronine

30
Q

phosphodiesterase

A

cGMP –> GMP

31
Q

NO binds to convert what

A

GTP -> cGMP

32
Q

oncotic pressure

A

pulls water from interstitial back to plasma

33
Q

ultrafiltration

A

hydrostatic pressure > oncotic pressure
(water move into tissues)

A

anti complement binds
antiphagocytic
needed for infection to occur

40
Q

streptodornase viruelnce factor

A

depolyermize DNA in pus

41
Q

hyaluronidase virulence factor

A

breaks down hyaluornic acid in CT making tissue MORE PERMEABLE

42
