Probably you refer to polyps, which are abnormal growths and can be dangerous.

The small intestine is covered in millions of villi what are villi and what is their job?
Villi are fingerlike projection from a surface and in the intestine they are one cell thick with blood vessels and lacteal. The funciton is to increase the surface area of the intestine and so increasing the ammount of absorption.
What is the function of projection?
They increase the surface area of small intestine and thus, increase the rate of absorption of food...
What are fingerlike projections of cytoplasm?
Fingerlike projections of cytoplasm and known as pseudopod(s). Pseudopd organisms are typically found on in the microscopic subkingdom of Protozoa( genus Amoeba).
Are finger like projection inside the Small intestine?
Microvilli for increase surface area for absorption
What are the fingerlike projections that greatly increase the surface are of cells?
stereocilia
What has tiny fingerlike projects that increase a cells absorption capabilities by increasing its surface area?
Villi are tiny fingerlike projects that increase a cells absorption capabilities by increasing its surface area.
Why does a small intestine needs an internal surface area?
You mean to say why does the small intestine have an internal surface area, well this is because there are micro-villi which are folded finger-like projection that each increase the amount of space food can be absorbed.
What is the absorptive surface area of the small intestine?
The absorptive surface area of the small intestine is actually about 250 square meters (almost 2,700 square feet) – the size of a tennis court! How is this possible? The small intestine has three features which allow it to have such a huge absorptive surface area packed into a relatively small space:1. Mucosal folds: The inner surface of the small intestine is not flat, but thrown into circular folds. This not only increases the surface area, but helps regulate the flow of digested food through your intestine.2. Villi: The folds form numerous tiny projections which stick out into the open space inside your small intestine (or lumen), and are covered with cells that help absorb nutrients from the food that passes through.3. Microvilli: The cells on the villi are packed full of tiny hair like structures called microvilli. This helps increase the surface of each individual cell, meaning that each cell can absorb more nutrients.
What part of the body absorbs nutrients?
The system in the body that absorbs nutrients is the digestive system. Within the digestive system is the small intestine. When food passes through the small intestine, villi, absorb all of the nutrients the body needs from the food. Villi are small fingerlike projections in the small intestine that increase surface area and "reach" out to the food and absorb its nutrients. So, to answer your question, villi that are in the small intestine within the digestive system absorb what nutrients our body needs.
What are tiny tubes sticking out of the wall of the small intestine?

Why is it important to increase surface area in the small intestine?
Millions of tiny hair-like protrusions, called villi, line the inside of the small intestine. They vastly increase the surface area of the intestines, to maximise diffusion of nutrients into the bloodstream. In fact, there are even smaller micro-villi covering the villi, to increase the absorption capacity even further! A constant supply of blood ensures a steep concentration gradient is maintained. This is a crucial factor for allowing as great an uptake of nutrients as possible.
How does the structure of the small intestine aid in the absorption of?
The small intestine is thrown into folds that increase its surface area by upto 600 times. This helps in the absorption by providing greater area for diffusion to take place through. Each villus (projection) also has a lacteal inside it, which helps in the absorption of lipids.
