(More specifically) long soft unmatted hair.
Villi, one of many tiny projections, containing capillaries and a lacteal, occurring over the mucous membrane of the small intestine that function in the absorption of nutrients and fluids.
A tiny hair-like or fingerlike vascular projection present on a mucous membrane. Villi are present in all three sections of the small intestine, but are largest and most numerous in the duodenum and jejunum (the first and second parts of the small intestine), where most of the absorption of food takes place.
One of many tiny hair-like or fingerlike vascular projections on certain mucous membranes in the body. Villi are present in ell three sections of the small intestine, but are largest and most numerous in the duodenum and jejunum (the first and second parts), where most of the absorption of food takes place.
One of many short fingerlike processes that project from some membranous surfaces. Numerous intestinal villi line the small intestine. Each contains a network of blood capillaries and a lacteal. Their function is to absorb the products of digestion and they greatly increase the surface area over which this can take place. Chorionic villi are folds of the chorion (the outer membrane surrounding a fetus). They are particularly numerous in the placenta, where they provide an extensive area for the exchange of oxygen, carbon dioxide, food, and waste products between maternal and fetal blood.
One of the minute processes thickly distributed upon the inner surface of the small intestine, giving it, to the naked eye, a velvety appearance, and greatly assisting absorption of digested food.
A small fold or projection of some mucous membranes.
A tiny, finger-like protrusion emerging from a membranous surface is referred to as a villus. In the mucous lining of the small intestine, there are millions of these villi. Within each intestinal villus, there exists a small lymph vessel along with a complex network of capillaries, which are minuscule blood vessels. The surface of the villus is covered with numerous hair-like structures known as microvilli. Collectively, these villi and microvilli create a significantly expanded surface area that facilitates the absorption of nutrients from the intestine into both the bloodstream and the lymphatic system.
A villus is a slender, protruding structure found on mucous or other membranes, with the intestinal villi being the most well-known. These intestinal villi extend into the small intestine’s cavity, housing blood vessels and lacteal vessels that facilitate the transfer of digested nutrients into the bloodstream. Villi are also present in the placenta, serving as a crucial link between the mother’s circulation and her developing fetus.
A small, elongated protrusion from the surface of a mucous or other type of membrane. Villi are found in various parts of the body, but the most commonly referenced are the intestinal villi. These project into the lumen of the small intestine and contain blood vessels and lacteal vessels, through which digested food enters the bloodstream. Villi are also present in the placenta, facilitating communication between the mother’s circulation and her unborn baby.
