Villi are found in our small and large intestines, and are adapted to their function by having a very large Surface Area to volume ratio. They are vital as they extract the vital nutrients from the food we eat and are absorbed into the blood supply which runs just underneath the villi, and transport these nutrients to wherever they are needed.

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 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.
Which systerm is important for breaking down food so cells absorb the nutraints?
The digestive system is responsible for breaking down food into nutrients that can be absorbed by cells through the process of digestion. Nutrients are absorbed into the bloodstream from the small intestine and transported to cells throughout the body for energy, growth, and repair.
What kind of digestive system does a shark have?
Sharks have a simple digestive system that consists of a stomach and intestines. They lack a pancreas and gallbladder, so they rely on their liver for producing enzymes for digestion. Sharks are known for having a relatively short and efficient digestive process.
What happens if there are no villi?
Without villi in the small intestine, nutrient absorption is significantly impaired. Villi increase the surface area available for nutrient absorption, so without them, the body would struggle to extract essential nutrients from food. This can lead to malnutrition and other health issues.
How the villi help in digestion?
Villi absorb nutrients in the remaining food through diffusion. The villi are shaped in microscopic hair-like waves so that they have greater surface area, therefore enhancing the diffusion process.
Why are there so many villi in air sacs?
just needs it to continue process
What similaritys exist in the digestive system of frog and man?
Frog's digestive systems have no villi, while human's digestive systems do.
Why are there so many different stuctures in the digestive system?
There are so many structures in the digestive system because the the food can be digested very easily and broken down into soluble food material and absorbed by the finger like projections villi and absorbed into the human cells.
What does does villi do in digestion?
The wall of the small intestine has folds that bear fingerlike prjections called villi. Villi in turn have projections called microvilli. The products of digestion are absorbed by microvilli and they enter the blood capillaries and the lacteals of the Villi.
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.
Why are villi so small?
Villi are so small because they are only made of one cell- they are single celled organisms
Why is the digestive so important?
because we wont eat without it
How is the structure of the villi adapted to their function?
The villi is only one cell thick so it easier to absorb.
How does the digestive system help the circulatory system?
The digestive helps the circulatory system by bring cookies to the lungs so the lungs can do their normal function, of helping the teeth to chomp down on food. It also helps by the lungs make donuts for the heart so the heart can stop beating.
Why drinking sufficient water is important in the absorption of the end products of digestion in the small intestine?
Drinking water is important because it helps to dissolve foods so therefore they can be soluble molecules that can be absorbed into the bloodstream by villi. Villi are finger like features in the small intestine which increase the surface area.
The main function of the human digestive system is to-?
The primary function of the digestive system is to disassemble food we consume into its component molecules, so it can be used as energy for the body. There are many stages in the process of digestion.
