Microvilli vs cilia?
Microvilli are microscopic cellular membrane protrusions that increase the surface area of cells, and are involved in a wide variety of functions, including absorption, secretion, cellular adhesion, and sensing mechanical signals. From Yahoo: A cilium waves, resulting either in motion of the cell, or motion of the material over the surface of the cell. In humans, you’ll find these lining the respiratory tract, to move fluid (and small particulates) out of the lungs. A microvillus does not wave. Its function is to increase the surface area of the cell, to increase the rate of diffusion of materials into the cell. In humans, you’ll find these on cells lining the small intestines, where you’d want to absorb the small molecules that have resulted from digestion of food you ate. Q: Frozen diaphragm A: We were more or less right.
