Intestinal villi. Cutaway computer artwork of villi (brush-like) in adipose (fat) tissue from the intestine. Villi are numerous tiny, finger-like projections on the epithelial lining of the intestinal wall. They provide a greatly increased surface area to aid in the absorption of nutrients released during digestion. Here, they are absorbing fats (lipids, yellow dots), which are stored in the tissue below.
