1/4 Synonyms: none The small intestine is the longest part of the digestive system. It extends from the stomach ( pylorus) to the large intestine ( cecum) and consists of three parts: duodenum, jejunum and ileum. The main functions of the small intestine are to complete digestion of food and to absorb nutrients.

How the Intestinal Villi Help With Digestion

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.

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.

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.
