Functions of lung cells Flashcards
1
Q
Goblet cells
A
secrete mucus
2
Q
Mucoserous glands
A
supplement secretions by goblet cells in the epithelium
3
Q
Club cells
A
secrete surfactant, enzymes that detoxify inhaled xenobiotic compounds, antimicrobial peptides and cytokines
4
Q
Type I pneumocytes/alveolar cells
A
remove surfactant and small particulate contaminants partly through pinocytosis. Contains simple squamous cells which are thin and thus good for diffusion
5
Q
Type II pneumocytes/alveolar cells:
A
contain lamellar bodies containing lipids, phospholipids and proteins that make up pulmonary surfactant
6
Q
Alveolar macrophages (dust cells)
A
immune cells present in both the alveoli and in the interalveolar septa
