Study Notes
Histology of the Respiratory System
Components of Respiratory System
- The respiratory system consists of two main parts: extrapulmonary and intrapulmonary.
- Extrapulmonary components include:
- Nasal cavity
- Larynx
- Trachea
- Primary bronchi
- Intrapulmonary components include:
- Conducting portion (responsible for gas exchange)
- Secondary bronchi
- Bronchioles
- Terminal bronchioles
Respiratory Portion
- The respiratory portion of the respiratory system consists of:
- Respiratory bronchiole
- Alveolar duct
- Alveoli (where gas exchange occurs)
Nasal Cavity Functions
- The nasal cavity has two main functions:
- Olfactory function (sense of smell)
- Respiratory function (process of taking in gas and producing energy)
Olfactory Epithelium and Respiratory Epithelium
- Olfactory epithelium is a type of tall pseudostratified columnar epithelium.
- Olfactory epithelium consists of three distinct cell types:
- Supportive cells (subcentriocular cells) with oval-shaped nuclei
- Basal cells
- Neuroepithelial olfactory cells with oval-shaped nuclei, differing in location and shape from supportive cells.
