What is ciliated epithelium?
Tissue lining organs like the trachea
What cells make up ciliated epithelium?
Ciliated epithelial cells and goblet cells
What is the function of goblet cells?
Release mucus to trap pathogens
What is the function of ciliated epithelial cells?
Sweep mucus away using cilia
What is cartilage?
