Villus | Structure, Function & Location | Britannica
网页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. The villi of the small intestine project into the intestinal cavity, greatly.
Intestinal villus - Wikipedia
网页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 collectively form the striated or brush border .
Villi: Definition, Function, Anatomy - Verywell Health
网页2023年3月9日 · Intestinal villi are tiny, finger-like projections made up of cells that line the entire length of your small intestine. Villi absorb nutrients from the food you eat and then shuttle them into your bloodstream so they can travel where they're needed. If you don't have functioning intestinal villi, you will experience malabsorption.

22.13A: Absorption in the Small Intestine - Medicine LibreTexts
网页The function of the plicae circulares, the villi, and the microvilli is to increase the amount of surface area available for the absorption of nutrients. Each villus transports nutrients to a network of capillaries and fine lymphatic vessels called lacteals close to its surface.
Intestinal villi - e-Anatomy - IMAIOS
网页The intestinal villi (villi intestinales) are highly vascular processes, projecting from the mucous membrane of the small intestine throughout its whole extent, and giving to its surface a velvety appearance.
23.6 The Small and Large Intestines – Anatomy & Physiology
网页Within the circular folds are small (0.5–1 mm long) hairlike vascularized projections called villi (singular = villus) that give the mucosa a furry texture. There are about 20 to 40 villi per square millimeter, increasing the surface area of the epithelium tremendously.
Intestinal Villus - an overview | ScienceDirect Topics
网页The vascular pattern of the intestinal villi is essentially the same from the duodenum to the ileum. Each villus is supplied by a central artery, which runs through the center of the villus toward the tip. It then divides into two narrow arterial trunks, which run directly below the epithelial cells downward toward the base of the villus.
22.10B: Histology of the Small Intestine - Medicine LibreTexts
网页Intestinal villi (singular: villus) are tiny, finger-like projections that protrude from the epithelial lining of the mucosa. Each villus is approximately 0.5–1.6 mm in length and has many microvilli (singular: microvillus), each of which are much smaller than a single villus.
