- CFunction: Forming a diffusion boundary Location: Air sacs of lungs and walls of blood vessels
- DFunction: Moving particles in a specific direction Location: Inner lining of blood vessels and tubular parts o
Correct answer
A. Function: Moving particles or mucus in a specific direction Location: Inner surface of hollow organs like bron
Step-by-step solution
According to NCERT, if the columnar or cuboidal cells bear cilia on their free surface, they are called ciliated epithelium. Their primary function is to move particles or mucus in a specific direction over the epithelium. They are mainly present in the inner surface of hollow organs such as bronchioles and fallopian tubes. The lining of the stomach and intestine has simple columnar epithelium (secretion and absorption), while the air sacs of lungs and walls of blood vessels have simple squamous epithelium (forming
