Minute fingerlike or tonguelike processes projecting from the free surface of the mucous membrane of the small intestine. They consist of a central part, or core, formed by a projection of the mucous membrane and a few longitudinally arranged muscular fiber cells from the muscularis mucosae. The core of the v. contains a closely set network of blood vessels and one or more lacteal trunks with a cecal termination near the free end of the v.
