1

Warms, humidifies, and filters air but does not participate in gas exchange

Anatomic Dead Space

2

Pseudostratified ciliated columnar cells

beat mucus up and out of lungs; extend to beginning of terminal bronchioles

3

Cells of Respiratory bronchioles

Mostly cuboidal

4

Cells of alveoli

simple squamous cells

5

97% of alveolar surfaces; squamous and thin for gas exchaneg

Type I pneumocytes

6

Precursor for Type I pneumocytes; secrete surfactant

Type II Pneumocytes

7

Dipalmitoylphosphatidylcholine

Most important lecithin in surfactant

8

When surfactant synthesis begins

week 26; mature levels at week 35

9

Amniotic fluid level for fetal lung maturity

Lecithin-to-sphingomyelin ratio >2.0

10

Club (Clara) cells

Non-ciliated; low-columnar.cuboidal with secretory granules. Secrete part of surfactant; degrade toxins; act as reserve cells

11

Lobes in right lung

3 lobes
