villus, in anatomy any of the small, slender, vascular projections that increase the surface area of a membrane. Important villous membranes include the placenta and the mucous-membrane coating of the small intestine.

Intestinal villi (sg.: villus) are small, finger-like projections that extend into the lumen of the small intestine. Each villus is approximately 0.5–1.6 mm in length (in humans), and has many microvilli projecting from the enterocytes of its epithelium which …

Apr 6, 2025 · Villi are tiny, flexible projections that line the lumen of the small intestine (the 9- to 16-foot section of the intestine situated between the stomach and large intestine). Villi are extremely small, ranging from 0.5 to 1 millimeters in length (0.02 to 0.04 inch).

Evaluating the villus – from normal to abnormal. This brief review emphasises the complexity of the structural, cellular, non-cellular, and gene-based aspects of villus-orientated biology, exemplifying, over the last 50 years, the vast expansion in …

: one of the tiny finger-shaped processes of the mucous membrane of the small intestine through which digested food is absorbed.

Nov 6, 2024 · Villi are tiny, hair-like projections and tissues composed of the cells lining your small intestine's inside walls. They serve a critical role in digestion, absorbing nutrients from food and...

Villus (Latin: "shaggy hair", pl.: villi) may refer to: Intestinal villus, refers to any one of the small, finger-shaped outgrowths of the epithelial lining of the wall of the intestine. Clusters of projections are referred as intestinal villi.

villi: Tiny, finger-like projections that protrude from the epithelial lining of the intestinal wall. plicae circulares: These circular folds (known as the valves of Kerckring or the valvulae conniventes) are large, valvular flaps that project into the lumen of the bowel.

In this study, we theoretically investigate the roles of the villus on cell turnover and propose that its finger-like shape tightly regulates shedding-cell ages; the villus limits epithelial cells from shedding early or staying in the epithelium for prolonged periods.

Structure of the villi —The essential parts of a villus are: the lacteal vessel, the bloodvessels, the epithelium, the basement membrane, and the muscular tissue of the mucosa, all being supported and held together by retiform lymphoid tissue:
