4) Pseudostratified Ciliated Columnar Epithelium
5) Goblet Cells
6) Sero-mucous Glands
60
Identify the slide
Bronchiole
61
Characteristics of Bronchiole histology.
* Cuboidal epithelial lining with cilia
* Smooth muscle
* No goblet cells
* No glands
62
Identify the slide
Respiratory Bronchiole
63
Idenfity the slide and structures
Alveolar duct
1. Smooth muscle
2. Avleolus
3. Respiratory bronchiole
4. Alveoli
5. Alveolar sac
64
Identify the slide and structures
Avleoli
1. Macrophage (dust cell)
2. Type 1 pneumocyte
3. Type 2 pneumocyte
65
Type 1 Pneumocyte
* Simple squamous (flattened for gas exchange)
* Covers 95% of alveolar surface (but only accounts for about 40% of pneumocyte population)
66
Type 2 Pneumocyte
* Cuboidal
* Produces surfactant
* Constitutes about 60% of the pneumocytes (but only 5% of the surface area)
67
What is external respiration?
Gas exchange across respiratory membrane of lungs (alveoli)
68
What is internal respiration?
Gas exchange across respiratory membrane in metabolizing tissues (skeletal muscles)
69
What is Cellular Respiration?
Series of metabolic processes where living cells produce energy through oxidation of organic substances.

Why do you think the hyaline cartilage rings of the trachea are "C" shaped rather than "O" shaped?
To allow the esophagus to expand into the trachea when consuming bolus.
