structures of the small intestine The inner wall of the small intestine is covered by numerous folds of mucous membrane called plicae circulares. The surface of these folds contains tiny projections called villi and microvilli, which further increase the total area for absorption.

The intestinal villi are small finger like projections that extend into the lumen of the small intestine. Each villus has many microvilli projecting from its epithelial surface, collectively forming a brush border. Villi are specialised for absorbtion and have very thin walls which are single cell thick. This enables a shorter diffusion path.

The coiled tube of the small intestine is subdivided into three regions. From proximal (at the stomach) to distal, these are the duodenum, jejunum, and ileum ( Figure 23.6.1 ). The shortest region is the 25.4-cm (10-in) duodenum, which begins at the pyloric sphincter.

Structure of Villi. The excessive percentage of villi gives a velvety appearance to the internal intestinal wall. Each villus carries a central core which is further made up of one vein, one artery, a muscle strand, a lymphatic capillary (lacteal) which is located centrally, and connective tissue that provides structures with support..

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: The lacteals are in some cases double, and in some animals multiple, but usually there is a single vessel.

The villi are small finger-like projections of the wall of the small intestine which extend into the lumen or interior space of the small intestine. As digestion is completed in the small intestine, the villi are then bathed in a fluid which contains the nutrient subunits the cells need.

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. Villi increase the internal surface area of the intestinal walls.

How the Intestinal Villi Help With Digestion
The villi begin primary development in the fourth week, becoming fully vascularized between the fifth and sixth weeks. Placental development begins with implantation of the blastocyst; this leads to its differentiation into several layers that allow nutrient, gas, and waste exchange to the developing embryo and fetus —as well as forming a.
