Where is the villi found

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. This is so that the contents in the lumen of the small intestine are constantly moving and the concentration gradient is maintained for efficient absorption. It is also believed that these contractions empty the contents of the lacteal into larger lymphatic vessels [1].

The villi is covered by a mucosal epithelium which is mainly composed of multiple cell types, enterocytes, goblet cells, enteroendocrine cells, and at the base of the villi also called a crypt paneth cells and stem cells, Enterocytes absorb substances such as water and electrolytes. Other cells such as goblet cells secrete mucus into the intestinal cavity and enteroendocrine cells secrete hormones. Paneth cells secrete anti-microbial peptides.

Intestinal villi are tiny, finger-like projections made up of cells that line the entire length of your small intestine.

Villi increase the internal surface area of the intestinal walls making available a greater surface area for absorption. Even before you eat, when you smell a tasty food, see it, or think about it, digestion begins. Saliva say: suh-LYE-vuh , or spit, begins to form in your mouth. When you do eat, the saliva breaks down the chemicals in the food a bit, which helps make the food mushy and easy to swallow. Villi are small finger-like outgrowths present that help in the process of absorption.

These are located in the inner walls of the small intestine. Its function is to increase the surface area of the small intestinal wall to absorb the digested food.. Villi are tiny, finger-like projections from the wall of the small intestine. They line the inner surface of the small intestine. Their role is to increase the surface area within the small intestine. This will lead to the increase of the surface area of absorption as it is the main function of the small intestine.

The inner lining of the small intestine contains numerous finger like projections called villi. The villi increase the surface area for absorption.
