Millions of tiny hair-like protrusions, called villi, line the inside of the small intestine. They vastly increase the surface area of the intestines, to maximise diffusion of nutrients into the bloodstream. In fact, there are even smaller micro-villi covering the villi, to increase the absorption capacity even further! A constant supply of blood ensures a steep concentration gradient is maintained. This is a crucial factor for allowing as great an uptake of nutrients as possible.
small finger-like projections called villi are present in small intestine which increase absoption area
because most of the food absorption is done in the small intestine.
villi and microvilli. they are fingerlike structures that extend from the inner surface of the intestine and absorb nutrients
Your small intestine has very large surface area to absorb the digested food material. The surface area of the small intestine is 2750 square feet. Much more than you can imagine.

Villi are fingerlike projection from a surface and in the intestine they are one cell thick with blood vessels and lacteal. The funciton is to increase the surface area of the intestine and so increasing the ammount of absorption.
The microvilli have finger-like shapes originating from the villi that line the small intestine. They greatly increase the surface area of individual cells when it comes to absorbing nutrients.
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.
Small intestine
Vili are present to increase the surface area of the small intestine. This allows more digestion to happen in the small intestine.

Villi or microvilli
Villi
finger like projections in small intestine are called villi to increase surface area for absorption of food in small intestine.
They increase the surface area of small intestine and thus, increase the rate of absorption of food...
