Ciliated cells are specialized cells that have tiny hair-like structures called cilia on their surface. These cilia work together in a coordinated motion, sweeping substances like mucus, trapped dust, and bacteria along the cell surface. This movement is essential for various functions in the body, such as:
- Clearing airways: In the respiratory system, ciliated cells line the trachea and bronchi, helping to remove mucus and debris from the lungs. This prevents infections and keeps the airways clean.
- Moving fluids: In the reproductive system, cilia in the fallopian tubes help to move the egg towards the uterus.
- Sensory perception: In the nervous system, cilia are involved in sensing fluid movement and detecting changes in the environment.
Examples of Ciliated Cells:
- Respiratory epithelium: These cells are found in the airways, and their cilia help to remove mucus and debris.
- Fallopian tube epithelium: These cells help to move the egg towards the uterus for fertilization.
- Ependymal cells: These cells line the ventricles of the brain and help to circulate cerebrospinal fluid.
Key characteristics of ciliated cells:
- Presence of cilia: These hair-like structures are responsible for the coordinated movement.
- Location: Ciliated cells are found in various organs and tissues, including the respiratory system, reproductive system, and nervous system.
- Function: Their primary function is to move fluids and substances along the cell surface.
