What are the tiny microscopic projections in the wall of the small intestines, which absorb nutrients into the bloodstream called?

Microvilli
Villus
Cilia
Villi

The correct answer is: Villi

The tiny microscopic projections in the wall of the small intestines are called villi. While microvilli, villus, and cilia may also be found in the small intestines, they do not specifically absorb nutrients into the bloodstream like villi do. Microvilli are found on the surface of some cells and are involved in absorption and secretion. Villus is a singular form of villi, and cilia are hair-like structures that help with movement and filtering in the body.
