villus sampling, Important villous membranes include the placenta and the mucous-membrane coating of the small intestine. 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. Each villus contains a specialized internal network of vessels that handles the transport of absorbed nutrients, differentiating between water-soluble and fat-soluble molecules.
