Question
Chapter 13, Problem 12SAE
Summary Introduction
To review:
The specific protective function of mucus secreted by tracheal goblet cells.
Introduction:
Goblet cells found in the trachea secrete mucus. This mucus is primarily composed of polysaccharides, globulins, and a mixture of inorganic salts. Mucus helps in the entrapment of foreign particles and facilitate their removal.

The mucosal portion of the trachea is lined with what type of cells?
One of the major features that distinguishes the trachea from the esophagus by histology is the
1) C-shaped hyaline cartilage
2) mucus glands
3) epithelia
4) muscle layer
Why is it important that the trachea is reinforced with cartilage rings? Why is it advantageous that the rings are incomplete posteriorly?

- What affect will a decrease in the acitivty of the lung's pneumocyte type II cells have on a person's breathing capacity? Explain.arrow_forwardMucous membranes (pseudostratified ciliated columnar epithelia) line most upper respiratory tract structures. Although these membranes filter the air by trapping pathogens in mucus, they are very delicate. Pieces of food passing through the oropharynx and laryngopharynx could damage this type of epithelium. Predict which type of epithelium protects the lining of the oropharynx and laryngopharynx.arrow_forwardA lifetime of heavy smoking often leads to destruction of the cilia of the cells that line the bronchi and bronchioles. How does this contribute to an increased chance of lung infections?arrow_forward
