Cilia in human health and disease

Cilia are tiny, hair-like structures on the surface of many human cells. They help with movement and sensory functions, playing critical roles in the respiratory system, reproductive organs, and brain. In health, they clear mucus from the lungs, guide egg movement in the fallopian tubes, and help detect environmental signals. However, diseases like cystic fibrosis and primary ciliary dyskinesia occur when cilia are damaged or absent, leading to respiratory problems, infertility, or other issues. Understanding cilia is essential as they are vital for various bodily functions and can significantly impact overall health when they malfunction.
