2

Lungs: Respiratory Portion

respiratory bronchioles, alveolar ducts, alveolar sacs, alveoli

3

Epithelium: trachea, main bronchi, lobar bronchi, segmental bronchi

pseudostratified ciliated columnar epithilium, goblet cells, submucous glands, hyaline cartilage

4

Epithelium: bronchioles

simple ciliated columnar to cuboidal, Clara cells

5

Epithelium: terminal bronchioles

simple cuboidal, ciliated, Clara cells

6

Epithelium: respiratory bronchioles

simple cuboidal, ciliated, Clara cells, scattered alveoli

7

Epithelium: alveolar ducts, alveolar sacs

simple cuboidal between many alveoli

8

Epithelium: alveoli

type I and II alveolar cells (pneumocytes)

9

Respiratory Tract: rhythmically moving back and forth to eliminate dust and germs from nasal passages

ciliated cells

10

Respiratory Tract: chemosensory

brush cells

11

Respiratory Tract: secretes mucus

goblet cells

12

Respiratory Tract: capable of regeneration and repair

basal cells

13

Respiratory Tract: metabolize airborne toxins

Clara cells / exocrine bronchiolar cells

14

Respiratory Tract: lines the alveoli

type I pneumocytes

15

Respiratory Tract: secretes surfactant and store it in lamellar bodies, capable of regeneration and repair

type II pneumocytes

16

Respiratory Tract: alveolar macrophage, antigen presenting cells

dust cells

17

Respiratory Tract Components: trachea, main bronchi, lobar bronchi, segmental bronchi, terminal bronchioles

goblet cells, submucous glands, smooth muscle, elastic fiber

18

Respiratory Tract Components: terminal bronchioles, respiratory bronchioles

smooth muscle, elastic fiber

19

Respiratory Tract Components: alveolar sacs

elastic fiber

20

Drug given to women to hasten surfactant production

corticosteroids (dexa-/betamethasone)

21

Determines fetal lung maturity from amniotic fluid sample

L:S ratio (lecithin : sphingomyelin)

22

Cells seen in lungs in the presence of CHF

hemosiderin-laden macrophages (heart failure cells)

23

Respiratory Tract: equalize air pressure in alveoli, permit collateral circulation of air when bronchiole is obstructed

alveolar pores of Kohn

24

Respiratory Tract: surfactant layer, type I pneumocytes, fused basal laminae of cells lining alveolus and endothelial cells, capillary endothelial cells

blood-air barrier

25

Imbalance of pressures in pulmonary capillaries causing edema

hydrostatic - out, oncotic - in

26

Protein important in the maintenance of adequate oncotic pressure to prevent edema

albumin
