Both are found inside the small intestine, are microscopic, and are used to increase the surface area of the small intestine. Villi are tiny microscopic folds in the small intestine lining. Microvilli are little hairlike projections from individual epithelial cells of the small intestine. They have capillaries and a lacteal that lead to the circulatory and lymph systems to transport nutrients that are absorbed.
Cillia is found in the trachea whereas villi/microvilli is found in the lumen of the small intestine
Yes. A villi is a fingerlike structure in a small intestine that absorbes the nutrition from the food you ate. A microvilli is basically a villi on a villi which is what actually does the absorbing
The intestinal wall has invaginations (or dips) that have a much larger surface ares compared to a simple tube
Microvilli, villi, plicae circulares, if choosing just one i would go with microvilli because the tremendously increase the surface area for absorption in the absorptive cell
In the ileum, (3rd part of small intestine after the 1st, duodenum, then the 2nd, jejunum) is where the villi and microvilli are. The villi are folds of the illeum wall, and their purpose is to increase the surface area. They are finger-like projections. These folds, or finger-like projections, have further projections on their surface. So in other words the villi have villi on them. But they are called microvilli. They are also to further increase surface area. The villi and microvilli are there for absorption. This is where most of the absorption of the nutrients from digestion occur(a fraction in the stomach wall).These nutrients are absorbed by diffusion into a capillary in the villi. Except for the fatty acids, which are absorbed by the lacteal in the villi. The villi are very thin. This allows diffusion to occur easier as it is close to the surface. The capillary and lacteal are close to the surface for the same reason. The villi are also semi-permeable, allowing only certain molecules to diffuse, and not diffuse the other way round. The nutrients, absorbed by the capillary in the villi, are now in the blood stream where they can be used as energy and proteins are sent to the liver to be broken down into amino acids to be arranged into the protein again that the body wants. Eventually some nutrients become part of your tissue (assimilation)I hope this somewhat helps. :)but hey, im 16, what do I know. you may want to check I'm right. :)

Villi
If the villi of the intestines had no microvilli, the absorption rate of the intestines would be significantly reduced. Microvilli are tiny finger-like projections on the surface of the villi that increase the surface area for absorption. Without microvilli, there would be less surface area available for nutrients to be absorbed into the bloodstream, leading to a decrease in absorption efficiency.
the villi or villus or microvillus or microvilli or muscosal villi
They are called villi(plural for villus).
Villi. Most absorbtion occurs in the ileum btw.
some one help me
Villi or microvilli
Villi and microvilli.
