1. embyronic (3-8)
2. pseudoglandular
3. Cannicular
4. Saccular
5. Alevolar (36+)

Question 2

Embyronic phase of lung development

Answer 2

lobar buds develop from the FOREGUT

Cells from the endoderm

Connective tissue - blood/vessels - mesoderm

Question 3

pseudoglander phase of lung development

Answer 3

branching of airways

primitive segmental bronchi

speacialised cells /cillia/mucous glands

Question 4

Cannicular phase 16-24 weeks

Answer 4

distal architecture = alveolar sacs, terminal bronchioles

T1/T2 pneuomyctes

Question 5

24 weeks is the limit of variability for foetus to be born

a. true
b. false

Answer 5

a. true

Question 6

Saccular phase

Answer 6

bronchioles elongates

more surfactant

alevolar sacs grow/well-formed

Alveolar stage

Answer 7

independently sustain breathing

developed structures
