    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.
