Pseudostratified columnar epithelium is found in which sites?

Explanation:
Pseudostratified columnar epithelium is characterized by cells of varying heights that all contact the basement membrane, often with cilia and goblet cells to help trap and move mucus. This type of lining is ideal for the airways, where sweeping mucus helps defend the respiratory tract. Therefore, its presence is most typical in the nasal cavity, trachea, and bronchi. The lining of the stomach is made of simple columnar epithelium specialized for absorption and secretion, not pseudostratified. The outer skin layer is stratified squamous epithelium, provides protection. Kidney tubules are lined with simple cuboidal epithelium, suited for selective exchange and transport.
