Respiratory

vocal cord – has two sides, true and false. ID by the epithelium. Stratified squamous non-keratinized is found in places that undergo wear and tear. It makes sense then that the true vocal cord will have this type of epithelium. It also has skeletal muscle underneath. The false vocal fold has respiratory epithelium (ciliated, pseudostratified columnar with goblet cells). There are also glands underneath.

  • Trachea – has hyaline cartilage, muscle, and respiratory epithelium

  • Lung – Many alveoli, know the two cell types: type 1-squamous types that allows for gas exchange, type 2 dome shaped cells that produce surfactant. The dust macrophages are larger, darker and are often located at the corners of the septa. A terminal bronchiole has no cartilage in the wall. The alveolar duct is a space that goes between what looks like alveoli that are broken open.
