Yes, cilia are like hair, specifically in their appearance as hair-like projections.
The following information helps elaborate:
- Structure and Location: Cilia are found lining the bronchus in the lungs.
- Function: These hair-like projections move microbes and debris up and out of the airways, helping to keep the lungs clean. The bronchus also contains goblet cells.
- Goblet Cells: Goblet cells secrete mucus, further aiding in protection by trapping microorganisms.
Therefore, while cilia aren't exactly hair, they share the characteristic of being hair-like projections and are crucial for respiratory health.
