MH 110 Trachea and Esophagus

Trachea

The is a tube that connects the larynx to the lungs allowing the passage of air. It is a fibromuscular tube supported by 15 to 20 "C"-shaped hyaline cartilages.

  • - the trachea is lined with a pseudostratified columnar epithelium with cilia and goblet cells.
    • Cilia - extend 5 to 7 µm from the surface of the columnar epithelial cells. The dark line at their base is from their basal bodies.
    • Goblet Cells - secrete mucus. They are difficult to identify in this specimen, but a thick layer of mucus (20 to 30 µm) is seen on the surface of the epithelium.
    • Basement Membrane - separates the epithelium from the underlying connective tissue. It is seen as a thick, eosinophilic band beneath the epithelium
  • - dense irregular connective tissue supports the epithelium.
    • - add moisture to air and aid in trapping contaminants. The cilia propel mucus towards the esophagus where it is swallowed.
  • - cross-section of a single, "C"-shaped that is open in its posterior aspect.
  • - that spans the ends of tracheal cartilages. They control the diameter of the trachea.
  • - loose connective tissue.
