Card preview (24)

#1
Front (Question)

consists of ciliated epithelial cells, goblet cells, and dendritic cells

Back (Answer)

conducting airway

#2
Front (Question)

• move bad things out - synthesize antimicrobial peptides

Back (Answer)

ciliated epithelial cells

#3
Front (Question)

produce mucus (protein called mucin with polysaccharide modification)

Back (Answer)

goblet cells

#4
Front (Question)

• hydrophilic • keep epithelia hydrated • made by goblet cells

Back (Answer)

mucin

#5
Front (Question)

what are the different types of mucin?

Back (Answer)

• membrane anchored mucin - polysaccharide secreted mucin

#6
Front (Question)

• intraepithelia - carry out surveillance

Back (Answer)

dendritic cells

#7
Front (Question)

consists of type 1 epithelial cells, type 2 epithelial cells, and macrophages

Back (Answer)

alveoli

#8
Front (Question)

• thin for gas exchange - provide the most coverage

Back (Answer)

type 1 epithelial cells

#9
Front (Question)

• rounded - produce surfactant

Back (Answer)

type 2 epithelial cells

#10
Front (Question)

• made by type 2 epithelial cells • protein + lipids • attached or secreted

Back (Answer)

surfactant

#11
Front (Question)

• carry out antigen presentation - phagocytosis to keep airway clear

Back (Answer)

alveolar macrophages

#12
Front (Question)

love the lipids in the airway

Back (Answer)

mycobacterium tuberculosis

#13
Front (Question)

how do the lungs of germ free mice compare to conventional mice?

Back (Answer)

have less mature alveoli

#14
Front (Question)

what happens if you give germ free mice Lactobacillus into the nose?

Back (Answer)

• develop normal lungs and normal # of alveoli - having bacteria in lungs helps develop structure

#15
Front (Question)

what happens during the flu in relation to resistance against bacterial infections?

Back (Answer)

decrease resistance against bacterial infections during flu

#16
Front (Question)

naked virus

Back (Answer)

non-enveloped virus

#17
Front (Question)

virus enclosed in membrane

Back (Answer)

enveloped virus

#18
Front (Question)

naked RNA of virus

Back (Answer)

icosahedron

#19
Front (Question)

*picornarvirus ~ssRNA ~icosahedron

Back (Answer)

rhinovirus

#20
Front (Question)

coronavirus

Back (Answer)

SARS (severe acute respiratory syndrome)

#21
Front (Question)

paramyxovirus

Back (Answer)

RSV (respiratory synctial virus)

#22
Front (Question)

involves replication of genome and proteins

Back (Answer)

virus replication

#23
Front (Question)

what are the steps of virus replication?

Back (Answer)

• attachment to host receptor • entry (at least genome) • synthesis - genome replicates and viral protein synthesis in host (in cytosol) • assembly of stuff that was synthesized • assembled virus particle needs to be released

#24
Front (Question)

virus particle with all its parts

Back (Answer)

virion
