Question:
What type of epithelium tissues are found in respiratory tract and in intestinal lining? How are these tissues different from each other?
Answer:
In respiratory tract and in intestinal lining, columnar epithelium are found. In respiratory tract, there is special type of columnar epithelium are found which are called ciliated columnar epithelium. These ciliated columnar epithelium have hair like outgrowth on their surface, called cilia. Cilia are capable of rhythmic movements in certain direction and their movement pushes the mucus forward to clear it.
