What is the primary function of ciliated columnar epithelium found in the respiratory tract?
Step 1: Understand what ciliated columnar epithelium is. It is a type of tissue that has tall, column-like cells with tiny hair-like structures called cilia on their surface.
Step 2: Know where ciliated columnar epithelium is found. It is mainly located in the respiratory tract, which includes the nose, trachea, and bronchi.
Step 3: Learn the function of cilia. The cilia move in a coordinated way to push substances along the surface of the epithelium.
Step 4: Identify what substances are moved. Ciliated columnar epithelium helps move mucus, which traps dust, germs, and other particles.
Step 5: Understand the importance of this movement. By moving mucus and trapped particles out of the respiratory tract, it helps keep the airways clear and protects the lungs from infection.
