Cerebrospinal fluid is drained into venous blood in the dural sinuses through structures called arachnoid granulations (also known as arachnoid villi or pacchionian bodies). These specialized projections of the arachnoid mater penetrate through the dura mater into the superior sagittal sinus and other dural sinuses, where they allow for the reabsorption of cerebrospinal fluid into the bloodstream.
The three types of villi are: Intestinal villi-microscopic finger like projections on the inner surface of the ileum. Chorionic villi-villi on the outermost membrane of the foetus. Arachnoid villi-villi on the arachnoid membrane of the brain.
Villi. Most absorbtion occurs in the ileum btw.
Villi are suited for their function because they greatly increase the surface area of the small intestine, allowing for efficient absorption of nutrients. Their structure includes a single layer of specialized cells called enterocytes that facilitate the absorption process. Additionally, villi have a rich blood supply and lymphatic vessels to transport absorbed nutrients quickly to the rest of the body.
They are called villi.

Villi is plural. One is Villus, many are Villi.
The small intestine contain a hair-like protrusion called villi. They aid in digestion by increasing surface area for nutrients to be absorbed. On those villi, there are absorption sites called lacteals. Lacteals are specialized vessels that absorb fatty acids.
The villi of the small intestine provide a large surface area that enhances nutrient absorption. These finger-like projections are lined with microvilli, further increasing the surface area and facilitating the efficient uptake of digested nutrients, vitamins, and minerals into the bloodstream. Additionally, the villi contain specialized cells that help in the absorption and transport of nutrients, contributing to overall digestive efficiency.
Yes, mammals have villi. An example is the villi in the intestines of humans which help to absorb nutrients.
