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 .
The villi of the jejunum look like long, finger-like projections, and are a histologically identifiable structure. While the length of the entire intestinal tract contains lymphoid tissue , only the ileum has abundant Peyer's patches , which are unencapsulated lymphoid nodules that contain large numbers of lymphocytes and immune cells, like ...
Drawing showing the relationship between villi and microvilli of the small intestine. The luminal surface of the enterocytes have microvilli (1 micrometer long) while the cell layer itself is folded to form villi (0.5-1.6 millimeters long) and crypts. Both serve to increase the total absorption surface of the intestine.
Stereocilia (or stereovilli or villi) are non-motile apical cell modifications. They are distinct from cilia and microvilli , but are closely related to microvilli. They form single "finger-like" projections that may be branched, with normal cell membrane characteristics.
The small intestine supports the body's immune system. [20] The presence of gut flora appears to contribute positively to the host's immune system. Peyer's patches, located within the ileum of the small intestine, are an important part of the digestive tract's local immune system. They are part of the lymphatic system, and provide a site for ...
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
Positioned on Broadway, in Manhattan, New York City, is the Charging Bull Statue, also called the Bull of Wall Street. The 7,100-pound bronze sculpture is 11 feet high and 16 feet long.
Illustration of the brush border membrane of small intestinal villi. A brush border (striated border or brush border membrane) is the microvillus-covered surface of simple cuboidal and simple columnar epithelium found in different parts of the body. Microvilli are approximately 100 nanometers in diameter and their length varies from ...
