It increases the surface area of the inside of the intestine, this allows for more area where nutrients can be absorbed.

What are finger like projections found on the walls of the small intestine?

Villi or singularly villus.


What is the name of projections on the inner surface of the small intestine?

The minute structures that project from the inner walls of the small intestine are called villi. They help in the digestion process by continuously pushing digested particles in one direction. Their function is to absorb nutrients. These villi effectively increase the surface area of the intestine so more nutrients can be absorbed.


What remains in the small intestine after all the nutrients have passed through its walls?

All the broken down foods that are too large to pass through the walls of the small intestine enter the large intestine, then in the large intestine the food is all pushed down removing any waters and then it finally comes out the anus. (:


Hair-like structures lining the walls of the small intestine are called?

The Villi


How does the structure of the small intestine improve its nutrient absorption?

1. The small intestine is LONG- this ensures food remains in the small intestine long enough for the products of digestion to be fully absorbed into the bloodstrem. 2. The Small intestine is HIGHLY FOLDED into villi (s. villus)- This gives a greater surface area for more efficient diffusion of products into the bloodstream. 3. The small intestine has a RICH BLOOD SUPPLY - Each villus has a network of capillaries so that the products of digestion are carried away from the small intestine efficiently. 4. The epithelium of the small intestine in the villi is only ONE CELL THICK - for easier diffusion of the products of digestion into the bloodstream. The walls of the capillaries are only one cell thick as well!!

What are the walls of the small intestine covered with?

The lining is plicae circulares, and the raised finger-like parts of the lining are called villi. Villi's adsorb carbohydrates through their membranes and capillaries within carry the nutrients off to the rest of your body.


Where does abscription of water and other needed materials for life take place?

The absorption of water and other essential materials for life typically takes place in the small intestine in humans. The walls of the small intestine are lined with villi, which are small finger-like projections that increase the surface area for absorption. Nutrients such as water, vitamins, minerals, and sugars are absorbed through these villi into the bloodstream.

Why do you have 20 feet of small intestine?

The small intestine is the main digestive organ of the human body. It is where digestion is completed and nearly all absorption of nutrients into the blood stream occurs. Because it has such a big job to do, it needs a large surface area so that more nutrients can be absorbed at any one time. This surface area is provided mainly by its length. The walls of the small intestine are also covered in 'fingerlike' projections called villi, on which are more tiny projections called microvilli. These projections also significantly increase the surface area of the small intestine, to allow a faster rate of absorption.

Why the walls of small intestine is not digested?

There is a coating that protects the small intestine from the acid used for digesting food.


How does food get out of the small intestine and into the blood?

Nutrients are absorbed through the walls of the small intestine into the bloodstream by diffusion or active transport. The structures in the walls of the intestine that allow this to happen are villi, which resemble finger-like projections. They are very well adapted to absorbing nutrients, thanks to a huge surace area, thin cell walls to make diffusion more efficient, and a rich blood supply to keep a strong concentration gradient.

What is the function of the small intestien?

It is to clear the unwanted substances to the large intestine and the wanted substances will be absorbed by the walls of the small intestine by the blood.
