1. RESPIRATORY SYSTEM

3. Respiratory system is responsible for oxygen supply of cells and tissues
It includes conducting portion
Nasal cavity
Nasopharynx
Larynx
Tracheo-bronchial tree
And respiratory portion
Pulmonary alveoli

6. Respiratory type epithelium – pseudostratified ciliated
Ciliated cells
Goblet cells
Basal cells
Specialized olfactory area
Olfactory cells (modified bipolar neurons) with knobs (olfactory vesicles) and hair-like processes (olfactory cilia)
Supporting (sustentacular) cells

12. Tracheo-bronchial epithelium
Ciliated cells (30%)
Goblet cells (30%)
Basall cells (30%)
Brush border cells (3%)
Diffuse neuroendocrine (APUD) cells (3%)
Serous cells (4%)

19. Bronchiolar epithelium
Ciliated cells
Clara cells
Basal cells

23. Alveolar epithelium Pneumocytes type I (respiratory)
Pneumocytes type II (secretory)
Alveolar macrophages
Respiratory barrier
