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.Each of these microvilli are about 1 μm in length, around 1000 times shorter than a ...

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 increasing the surface area for food absorption and adding digestive secretions.

The meaning of VILLUS is a small slender often vascular process.

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 ...

Apr 6, 2025 · Intestinal villi (singular: villus)are tiny, finger-like projections that line the interior (lumen) of the small intestine. The primary function of villi is to absorb nutrients from food and transfer them into the bloodstream for use in the body. Villi are extremely small, ranging from 0.5 to …

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. Chorionic villi, found on the surface of the outermost membrane (the chorion) of the fetus; Arachnoid villi, located on the arachnoid membrane of the ...

This diagram represents the types of bone-marrow cell derivatives operative within the lamina propria. They include (in cerise) the subepithelial myofibroblast system (MYF); pericytes (green) supporting the subepithelial capillaries and main vasculature of the villi (artery, red: vein, blue); the lacteal (L) supported by smooth muscle cells (SM) and (purple) the muscularis mucosae (MM).

The intestinal epithelium consists of 2 regions known as the crypt, at the base, and the villus, at the tip. The crypt-villus axis provides the architecture necessary for continuous proliferation and replacement of dying and damaged mature cells of the epithelium. 34 This structure is critical for the functional elements of the intestinal epithelium: absorption, protection, and secretion.

Ans. Some of the conditions that can damage the villi are: Intake of protein gluten (found in wheat, barley, and rye grains) in celiac disease allows the immune system to attack the intestinal villi and slow them down (this process can also be termed as villous atrophy).
