The primary function of the small intestine is the absorption of nutrients and minerals found in food. Intestinal villus : An image of a simplified structure of the villus. The thin surface layer appear above the capillaries that are connected to a blood vessel. The lacteal is surrounded by the capillaries.

Digested nutrients pass into the blood vessels in the wall of the intestine through a process of diffusion. The inner wall, or mucosa, of the small intestine is lined with simple columnar epithelial tissue. Structurally, the mucosa is covered in wrinkles or folds called plicae circulares—these are permanent features in the wall of the organ. They are distinct from the rugae, which are non-permanent features that allow for distention and contraction.

From the plicae circulares project microscopic finger-like pieces of tissue called villi Latin for shaggy hair. The individual epithelial cells also have finger-like projections known as microvilli.
