Study Notes
Upper Respiratory Tract
- The upper respiratory tract includes the nose, nasal cavity, pharynx, and larynx.
Conductive Portion of the Respiratory System
- The function of the conductive portion of the respiratory system is to filter, warm, and humidify the air breathed in.
Overall Function of the Respiratory System
- The overall function of the respiratory system is to bring oxygen into the body and remove carbon dioxide from the body.
Alveolar Lining
- The alveolar lining is made up of about 95% type I alveolar cells.
Club Cells
- The function of club cells is to produce and secrete surfactant, which helps to reduce the surface tension of the air-water interface in the alveoli.
Respiratory System Components
- The respiratory system component that includes saclike alveoli in its wall is the bronchiolar-alveolar region.
Type II Alveolar Cells
- The main function of type II alveolar cells is to produce and secrete surfactant, which helps to reduce the surface tension of the air-water interface in the alveoli.
Mucous Production
- Goblet cells are responsible for mucous production in the respiratory epithelium.
Nasal Cavity
- The major role of the large venous plexuses in the lamina propria of the nasal cavity is to warm and humidify the air breathed in.
Larynx
- The vocal cords in the larynx are lined with stratified squamous epithelium.
Bronchi and Bronchioles
- The main difference between bronchi and bronchioles is that bronchi are larger and have cartilaginous walls, while bronchioles are smaller and have muscular walls.
